I have made a table and quered that table. I have a form that I designed and is working well. It updates the table like it is supposed to. The problem I have is when I go in and change the master table. I decided that instead of havinga field titled "Unlisted/Listed" I just made it Listed and you put a yes or no. But when I do that and go back to the form a box pops up asking for some value. How do I fix this? Thank you.
