bblustein,

I am also pretty green, but I think a good first step would be for you to post your code. If it's relatively short, drop it in some <code> tags and add it to your writeup. If it's long, put it in your scratchpad for everyone to take a look at (you can edit your scratchpad from your homenode--I just discovered this yesterday). Some of the error messages might also help.

That's the extent of my help. I don't know jack about Perl/tk...

AH
