Is it possible to prevent the message box that says "Your item is not on the list. . . ?" As explanation, I have code running on the not in list eventin a combo box, which requires that in the table the properties be set to only accept items in the list. Part of the code is a message box giving instructions, so now I have two boxes--mine and the system's. I have tried including a line of code to turn the system warnings off, but it still shows up. I'm wondering if I'm trying to do the impossible.
