Greetings Richard, I've spent the last couple mornings trying to resolve this issue without any luck. As far as I can tell I copied and pasted the "DiscountRate" text box on the CustomerF on to the OrderF and OrderDetaiF. I changed the Control Source to =Forms!CustomerF!DiscountRate and =Forms!OrderF!DiscountRate. When I open the OrderF from the CustomerF the DiscountRate From CustomerF is populated into the DiscountRate on both the OrderF and OrderDetailF but they are not editable. I checked the properties of the text boxes and "Allow Edits" is yes and the text boxes are not locked. I don't want to move forward until this is corrected as it may pose a problem later in course. Help!!!!

Would you not need the DefaultValue to be this instead of ControlSource?
