I am troubleshooting a problem on a database I did not create. I'm using Access 2000, and after the intial start up of the form a dialog box appears saying that there is an invalid key 'D'.- continue loading project. If I click No, the message repeats, click yes and the box is gone. It continues to appear on nearly any event. There is an autonumber field labled Key, in the primary table. I can not check the VB code because I get an invalid format error whenever I go into the viewer. This is a rather simple design, there are only a couple of queries and no relationships among the fields. I'm looking for any answers or methods to eliminating that error box. Thanks in advance!
