    NZ() IsNull... What does it all mean?!

    Ok...heres what I'm trying to do... I've set up two queries, one to create all the null values. The other to search based off the form. In criteria for [txtyear] to change fldYear I have: [txtyear] = Nz("[txtyear]","[frmSearch]","Null") This is returning as containing the wrong number of...

    NZ() IsNull... What does it all mean?!

    Thank you for your quick replies. It's still early in the day here and my brain isn't working at anywhere peak performance right now so these concepts are still a little fuzzy to me.

    Inventory Pricing (Changes in prices)

    This database is primarily for an inventory of road work (like job, employee's hours, and inventory used) I doubt that there will be multiple shipments of the same type of goods on the same day, most of the items worked with are salt/sand and diesel, I just need to be able to keep an approximate...

    Inventory Pricing (Changes in prices)

    I'm wondering, what if you separate out the inventory by date, so that each set of 'bought' inventory is tagged to a date, and then set up the system so that the 'oldest' date for that type of item is removed first? Obviously 'lot' would be separated in a table by date instead of just by type...

    Inventory Pricing (Changes in prices)

    I'm actually pretty new with this, but I'm a quick learner and I'm not eager to let my boss down, I'm going to read up on how to do this some more and will probably have some more questions later in the week as I'm going to avoid this part for a little while to get everything else in working...

    Inventory Pricing (Changes in prices)

    I discussed this with my boss and he said he would like me to record quantities/prices based on the FIFO method... I have no idea how to go about doing this. My plan was to store quantity values with price values, but if there are more than one price value, how am I to set up a table to reflect...

    Inventory Pricing (Changes in prices)

    Thanks for the advice Dave, I'll have to set up a meeting with my supervisor and see how he'd like to proceed. I wasn't even thinking of it in terms of final accounting measures so your bringing this to my attention was very important.

    Inventory Pricing (Changes in prices)

    I am trying to build a database that includes inventory information. What I am trying to do is have a way of storing a base (yearly or quarterly) inventory and then every time a job uses material it will be recorded and a search of inventory can produce inventory used and/or current remaining...

    Totals by Month and Year

    Hmm what I said wasn't clear at all. I have set up a Total Textbox, added it to the Page Footer, In Data I used Control Source: Price, and Running Sum: Over All, it only gives me the last piece of data though.

    Totals by Month and Year

    Thank you for your answer. I understand most of this other than the 'grouping footer' and the sum part. How do I create a 'grouping footer'? And How do I create a sum in it? Thanks again, A

The queries calculate the prices of each job based on...

    Multiple Questions from an Access and VB Newb

    This solution makes sense for coming up with a cost value, my problem is I'm trying to associate each text value in my 'job' list menu with a numeric hourly value for the job (so that whoever is inputting the type of job is not necessarily aware of it's hourly cost) how would I be able to work...

    Multiple Questions from an Access and VB Newb

    Thanks for taking the time to look at my problem. I hope this explains what I'm trying to do a bit better. Essentially, I'm trying to get a weekly cost value for each set of actions IE. If truck1 plows snow for 10 hours in a week at $22 an hour, i'd like to be able to access the price of $220...
