Need help from the experts, On my table I have created a field and called it "US Domestic" and another field called it "Int'l Export". these two fields Data Type (Yes/No). I've created a query and created a form to brings those two fields in. However, if the "Int'l Export" is checked on the form, then I want to make another/respective field a required field. For example. If the check the "Int'l Export" then parts number is a required field and must be filled out. Else, these fields are not required field. Is possible?
