View 1 RepliesI have it mostly working right now, I can edit existing data and have it save to the database so when I re-open the program all the new data is still there. Now I get an error saying "Column 'AppID' does not allow nulls." when I try to create a new record. AppID is a column in the DB that I use to number the appointments. I guess it's looking for this value when it tries to save the new data, and since it isn't a field on the form it doesn't get an entry and fires that message. I've tried changing the AppID column to an AutoNumber field so it generates by itself but I still get the same error.
