in reply to 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>

    yet 
    <!-- variables (index, desc) are (10, ) -->

    The previous instance of the CGI variable would have correctly had the desc parameter undefined, but *this* one seems to be set.
