My guess is you accidentally did some extra input.  Use Ctrl + W and look at the batch input for Screen 3. If you have anything in the code range of 900 - 999 delete it. OR just carefully look at all the input for Screen 3, especially toward the  end.

Thank for the idea, but there is nothing entered with those codes.  I'm thinking it is a software glitch as I haven't had a problem until recently.

is there any further information regarding this issue?  i have a nc partnership return with this error message.  i put in the bank account info, even though nothing is due, still have the error.  i have several other nc partnerships which actually owe and am not receiving this error.

I have not seen anything and it's very random as to when I get the diagnostic and when I don't.  So I just paper file if I get it and can't fix it.
