This message has been marked as the solution to the initial question of the thread.
If you look in the VFP Help file for GetFldState, this is expected return value for GetFldState when the record pointer is at EOF. This makes sense because you can not have a "field state" when the pointer is at eof. So revise your code to handle a NULL return value using the ISNULL() function. Or you could just not check for feild state if the pointer is at eof.
