I downloaded it because I found it at 2nd place at "Most downloaded"!, and I found it very useful. I just would prefer a WARNING message instead of a DISPLAY, in order to be able to avoid it and just looking into the .n field at the second output, which, by the way, was very clever.

Thanks us for the submission.
