Unanswered: Error 3058 (Index or primary key can't contain a Null Value)
I converted my Access 97 database to Access 2000 and now receive an Error 3058 whenever I try to add new records via my form. The form has subforms (tabs). I have 5 different tables that utilize the form for updating and adding new records. The master table has the projectId as the key (auto number), and the other tables use projectId as the key as well.
