When adding a new payment record (i.e. payment was received), i want to allocate that to one or more invoices previously sent. This I can do no problem using an ADD page in a Master-Detail setup. I look up the invoice in a dropdown from the invoice table and select the correct one(s) to include in the detail "Payment_Allocations" table. Great that works.
BUT, what I really want is to filter the dropdown on the Client_Id which is in the ADD page (but not yet submitted). IOW's I only want to see the invoices for that client in the dropdown on the ADD page. How can I grab the Client_Id and filter the dropdown on that before submitting?
