I am using a Combobox with recordsource type set to fields. I set a filter on the table to show just the records I want. If there are more than one records shown everything works fine, but if there is only one record the =seek(this.value) in the Valid does not work. If I first look up customer that has several orders, select one from the combobox and then select a customer with only one order it will work OK. Why does this behave this way?
