Analysis graphs for individual customers

[JimmyG]

My database records order details for analysis. I have created a form to monitor individual trends in orders placed by my customers. As we supply bespoke items each customer has a list of products which they alone purchase, i.e we do not supply stock items, each item is specifically for one customer (they can then buy the items on a regular basis). The products are assigned to a customer in the products table.

The Analysis form I have created displays the customers name and two graphs. The first graph shows total sales each month, this graph updates as I navigate through the records (i.e. a different graph is loaded for each customer). The form also contains another graph, this is where the problem lies! This graph shows orders of the individual products, controlled by a drop down list containing all the products we supply. I need to limit this list to only show those products relevant to the current customer select on the form. (The products are assigned to a customer in my products table). Currently I achieve this by using a query which when the form is opened asks me to enter a customer ID, the drop down list is then limited to the products supplied to that customer.

What I would like is for the drop down list to update as I navigate through the records. i.e. when customer A is displayed show all the products assigned to customer A, when customer B is displayed show all the products assigned to customer B.

I’ve attached a snapshot of the form to help explain what I mean.

Thanks for any suggestions.

If it helps I think what I need to do is filter the results of my combo box to only include those products which are assigned to the customer displayed. the filter would then need to update the combo box as the records were navigated.

I just included more detail in the first passage incase there was a better way which required more information!

Thanks
