Re: CGI scoping question

Why would index not be 10

Perhaps $q is not defined, add this line to check

die "\$q not defined" unless defined $q;
my $index = $q->param('orderby');

I'm using `$q` in the global, so having it vanish in the subroutine would be interesting indeed. Added that check line, but no joy. Just now I had a case where `<li><strong>orderby</strong></li> <ul> <li>10</li> </ul> <li><strong>desc</strong></li> <ul> <li>1</li>` [download] yet `<!-- variables (index, desc) are (10, ) -->` [download] The previous instance of the CGI variable would have correctly had the desc parameter undefined, but this one seems to be set.
