hi:    i have a problem when use dbform, i have two tables, one is ODS_CIRCUIT, another is ODS_CUSTOMER, there's a field called CUSTOMERID in ODS_CIRCUIT which references the field in ODS_CUSTOMER called ID, when i show the table of ODS_CIRCUIT, i want to show the customer's name ( a field in table ODS_CUSTOMER) instead of the CUSTOMERID, but none of them is the key, so how to do , how to reference the customer's name by customerid?   thanks!
