Error Copying Field Data use =Sum([])

[access2010]

Hello, using Ms Access 2003 we would like to copy 2 fields

SharesOwned by using =Sum([TransactionQuantity])

Net_Share_Cost by using =Sum([AverageShareCost])

But errors keep occurring.

A suggestion would be appreciated.

Thank you,
Nicole

Try this in the OnCurrent event of the parent form for the Quantity field:

Me.Net_Share_Quantity = DSum("[TransactionQuantity]", "Investments_Purchases_SalesT", "Symbol_Stock = '" & Me.Symbol_Stock & "'")

Apply the same method for the Cost field.

There are other ways to achieve this but in the interim, this is something for you to play around with.

Edit: If doing the above, remove the control source from the parent quantity textbox.

your transactionquantity is in a subform, you need to put your control in the header of footer of the subform.

however you already have that calculation in a control called SharesOwned, so refer to that instead

=[Investments_Purchases_SalesF_SubForm].[Form].[sharesowned]

Thank you for your suggestions.

We have used the following code with success.
=[Investments_Purchases_SalesF_SubForm].[Form].[sharesowned]

I/We do appreciate your help.

Thank you for your code which is working.

For some reason the data = Net_Share_Quantity = and =Net_Share_Cost = are not being saved into our table to be used in other forms.

Could you please advise me as to what I have done wrong?

Thank you

You have a design issue problem. I can see that in your primary investment table you have fields for NetShareQuantity and NetShareCost but you don't really need those fields in any table.

Simply calculate them, as you do for the main and subforms the subject of this thread. Where you require that information for other forms, base those other forms on queries, in those queries you calculate that information.

Another approach, utilise the OnCurrent method I mentioned previously (3 or 4 posts above). If doing this approach, with the query you wouldn't also calculate the same information.

I've only honed in on the two fields you've mentioned, I haven't analysed the rest of the fields in your tables.

Thank you for your suggestion, but we are all volunteers at a NGO (Charity) and can not figure out how to create the code which you have suggested.
Would you be kind enough to place Your Code into the data base that we have uploaded.

Thank you.

There is always more than one way to skin a cat. To answer your question, here is one way. I created three queries, each one builds upon the preceding one.

Query 1: (qryZ_01_CalculateLineTotals)

SELECT Investments_Purchases_SalesT.Symbol_Stock, Investments_Purchases_SalesT.TransactionQuantity, Investments_Purchases_SalesT.TransactionPrice, Investments_Purchases_SalesT.TransactionComm, ([TransactionQuantity]*[TransactionPrice])+[TransactionComm] AS LineTotalAmount
FROM Investments_Purchases_SalesT
ORDER BY Investments_Purchases_SalesT.Symbol_Stock;

This query includes one calculated field (LineTotalAmount) (I used the prefix Line, so I know I'm dealing with an acutal transaction line).

Query 2: (qryZ_02_LineItems) Is based upon Query 1 above:

SELECT qryZ_01_CalculateLineTotals.Symbol_Stock, Sum(qryZ_01_CalculateLineTotals.TransactionQuantity) AS StockQuantity, Sum(qryZ_01_CalculateLineTotals.LineTotalAmount) AS StockTotalPrice
FROM qryZ_01_CalculateLineTotals
GROUP BY qryZ_01_CalculateLineTotals.Symbol_Stock;

This query (a Totals query) merely sums the stock quantity and LineTotalPrice. LineTotalPrice was a calculated field from Query 1.

Query 3: (qryZ_03_StockAvgPrice) Is based upon Query 2 above:

SELECT qryZ_02_LineItems.Symbol_Stock, qryZ_02_LineItems.StockQuantity, qryZ_02_LineItems.StockTotalPrice, IIf([StockQuantity]>0,[StockTotalPrice]/[StockQuantity],0) AS NetStockAvgPrice
FROM qryZ_02_LineItems;

This query is required in order to extract and correctly calculate the average price per share, for what balance is remaining of a stock.

You will be able to copy the above queries directly into your db for testing, as long as you name them as I have indicated (qryZ_....). The only reason I named them like that is to keep them together at the end of the query list in your db.

What are you trying to achieve? I think you have misinterpreted the use and purpose of the three queries I provided. You haven't altered the form to suit those queries and incorrectly added three fields (that correspond to the three queries I provided) to your table. You already have two text boxes (Net Share Quantity & Net Share Cost) that correctly display the data. I compared the results of the query I provided against your existing form, the results are identical; so to my first question, what are you trying to achieve?

What you could do, is remove from the Parent form "Net Share Quantity" and "Net Share Cost" as that information is duplicated, you have it displayed in the sub-form.

As an aside, what is NGO? What do they do?

Thank you for your note.
Most of the staff in our office are Volunteers and our Director would like to see the, "Net Share Quantity" and "Net Share Cost" on the Main Browse form and on other forms and in reports.

Our difficulty is that EVERY December we receive MANY DIFFERENT EQUITIES as donations and the donors receive tax receipts for their donations. Some of the equities are duplicates and when our organization needs funds we sell some equities.

At this time we would like to have these values visible on different forms and reports.

Any assistance you can provide will be appreciated.

I'm not sure how much headway we can make here. It seems like you are struggling with the underlying table structure (my three queries, case in point). By headway, I mean to continue with form design and implementation based on current table design.

To address the table design that will require some concerted study on your part. It is a dry topic, but when you get your head around it, other things fall into place. This is a good starting point.

To address directly your question that you could not get my queries to work, this is how they could be implemented.

Query number 3 (qryZ_03_StockAvgPrice) is used to create another query (qryZ_04_StockSummary) that will be the recordsource of your parent form (yours copied to sat_Investments_Purchases_SalesF). In that parent form, the 'Net Share Quantity' and 'Net Share Cost' have Control Sources directly from the forms recordsource.

If you check the query (qryZ_04_StockSummary) that is the recordsource of the form, you will see that, if you wanted to, you could add other relevant fields from your Investment table. (I've attached your db)

As previously mentioned, I've named the queries and form in that style for ease of my reference.

Thank you for the link to the article.

We are still trying to understand how to obtain the information that our Director wants, which we are still working on to-day.

Could a Update Query as you suggested to Crystal, which works for her problem, be used to copy the "Net Share Quantity" and the "Net Share Cost" onto the Main Browse form and onto other forms and in reports?

Thank you

Did you check the form, "sat_Investments_Purchases_SalesF" that is a copy of your form, prefixed with "sat_". The ''Net Share Cost' and 'Net Share Quantity' (or Avg Price, can't recall at the moment) are already displayed on your main browser form, they were calculated, that is what I provided above. I don't understand why they need to be copied, copied to where? Where ever that information is required, calculate it.

An Update Query updates data in tables, is this what you mean by copying the data? I'm suggesting you shouldn't store calculated fields in tables. If you really want to take this approach, from your other thread, simply follow along and substitute the various Form and Field references to suit.

I haven't got access to you db at the moment, so can't check it in detail.

Query Required for Calculation

We would like to create a query to find our {Average Share Cost} as the calculation we had been using is not acceptable with our accountant.

We should find the total $ value of all {Bought_$} plus all {DRIP} transactions and then divide their total $ by the number of {Shares Owned}

Thank you,

You'll have to explain to me what is 'Drip' when batched together with 'Bought_$ and Sold_$.

I've perused your latest db but can't do anything useful with it at the moment.

 

[essaytee]

Try this for starters.

You need to edit Query 1 (qryZ_01_CalculateLineTotals) by adding in the field, "TransactionType". In the Criteria columns, enter "Bought_$" and in the same column below, enter "Drip". That will restrict the query to only retrieve records marked as "Bought_$" or "Drip".

The full query is as follows:

SELECT Investments_Purchases_SalesT.Symbol_Stock, Investments_Purchases_SalesT.TransactionQuantity, Investments_Purchases_SalesT.TransactionPrice, Investments_Purchases_SalesT.TransactionComm, ([TransactionQuantity]*[TransactionPrice])+[TransactionComm] AS LineTotalAmount, Investments_Purchases_SalesT.TransactionType
FROM Investments_Purchases_SalesT
WHERE (((Investments_Purchases_SalesT.TransactionType)="Bought_$")) OR (((Investments_Purchases_SalesT.TransactionType)="Drip"))
ORDER BY Investments_Purchases_SalesT.Symbol_Stock;

Copy the above and enter it into the SQL View of Query 1.

Does this get close to the figures you're after?

As an aside, I noticed that the TransactionQuantity per line is either positive or negative. The negative entries relate to 'Sold_$'. Without directly referring to the Transaction Type (Bought, Sold, Drip) it would be possible, in the query, to only restrict entries where the TransactionQuantity > 0 (must be either Bought or Drip (what ever Drip is)).

If I am speaking out of turn here, I am sure I will be admonished.

However PMFJI,

I have helped and tried to help you in the past, but NGO or not, you need someone who stays for the duration.

You cannot expect people here to retrain users each month or months on aspects of Access that have already been explained.?

I happy to say this, as I am also volunteer for a charity, but I am prepared to stay with it until circumstances change dramatically for me, and I do not expect others to do the work for me.? I will ask for assistance obviously, but not repeat the request.

There is asking for help, and then there is just taking plainly taking advantage.

I feel you are now doing the latter.?

My 5 cents as the USA will say.
