I'm trying to display sales transactions in a grid for the currently selected customer. When I run the form and select a customer with known sales transactions, one line item is displayed for a split second, and then the grid goes blank. The relating field is the customer id. I get the same results when using the one-to-many form designer. There are 7000 records in the sales table. I have had success with a smaller 10 record test table. Does the record number have anything to do with my problem?
