Linda,

>My form has two drop down lists. The first has a store no. When a store no. is selected, it calls the code to get a list of all the invoice numbers for that store and uses a 2nd table (InvoiceList) from the invoice business object to populate the drop down list of invoices. When I step through the code after selecting a store, the error "Missing Operand" occurs in the filldataset command. The correct value of the store number has been passed in.

This is complex enough that it would be best if I looked at this on your computer. Why don't you shoot me an e-mail tomorrow and I'll take a peek.

Best Regards,
