Could it be that you made changes in another file/location? Perl can't possibly invent variables/variables.cgi if you specified a full path. Just to be clear, the error you cite can be eliminated by changing line 44 of C:/strawberry/perl/site/lib/UltimateAuction.pm to a full path. And since you are there put a comment that this needs changing whenever you relocate your code.

Or use this method Re^7: Sorry.. Same problem but some progress! and Re^7: Sorry.. Same problem but some progress! to do it once and for all. Caveat: I hope Apache takes that variable into consideration when spawning your scripts.
