I'm pretty much a newbie and should be reading more than contributing, but
one of my professors insisted that we troubleshoot all of our classroom
assignments by running our Perl programs from the command line. I've
continued this practice in my post-classroom life.

I wish I new. The browser just says "There is an Internal Error. Cotact the

What error are you getting? As far as I can tell, that line would print
"Hi Dude (project_number) <BR>\n"
rather than give an error ($resultCat being undef).
