I didn't really consider this option as I suppose I would never assign a product to ID 0. Zero isn't really a number, therefore why would I assign a product to a not-really-a-number ID? :P Anyway, if you really did need part 0, then just change `while (!$part \|\| $part =~ /[^0-9]/) {` to `while (!defined $part \|\| $part =~ /[^0-9]/) {`. The only thing this will also change is if the user hits enter without entering anything, the program will exit. That's fine by my standards	[reply] [d/l] [select]
