At one point I asked what ISEXCLUSIVE(). was returning and he said .F...I don't know what happened in the code after that or how his ON ERROR is setup. But like I said, he's dead in the water until that is fixed first. The real question here is WHY cant he not get exclusive use of the table - and this can be narrowed down pretty easily if that becomes the focus here.
