I have an access form with Data Entry set to yes. I've been using the database for over a year with no issues and now it's not letting me open just this one form. The database has a front and back end, and when this began malfunctioning yesterday, I assumed it was a problem with my local front end, but now another user is telling me that he's having the same problem. The form opens in edit mode with no problem at all. Please help.
