Okay, I've narrowed down the problem to the line

$_ =~ s/\$(\w+)/$formdata{$1}/eg;
[download]

I'm not exactly sure what the problem with this line is, seeing how it works at a previous occurence of the exact same line. When I comment out this line, however, the HTML is displayed in full, but none of the form field values are replaced. Does anyone see the mistake? ?????
