The comma was putting it into its own <td>

Hrmmm... I cut/pasted your code and it worked for me...

Here's the full code I was using.

print     $q->header(-type=>'text/html'),
    $q->start_html(    -title=>'User Setup',
            -bgcolor=>'#ffffff',
            -onLoad=>'Javascript:document.houst.userid.select()'),
    $q->start_form( -name=>'houst',
            -method=>'post',
            -action=>$me),
    $q->table( {    -align=>'center',
            -border=>0,
            -width=>400,
            -cellspacing=>10 },
            $q->Tr( [
                $q->td( { -align=>'center'},
                    [ $q->font({-face=>'arial', -size=>'+2'}, $q->b('U
+ser Setup'))]),
                $q->td( { -align=>'center'}, [ $q->hr]),
                $q->td( [ $q->textfield(-name=>'userid', -size=>'42', 
+-default=>'') ]),
                $q->td( [ $q->popup_menu(-name    =>'server_instance',
                            -values =>['cash_fidev','cash_sbltest'],  
+           # this is the actual argument passed to the server
                            -labels    =>{cash_fidev => 'Dev', cash_sb
+ltest => 'Test'}) ]),    # this is the corisponding label on the webp
+age
                $q->td( [ $q->submit (-value=>'Submit') . ' ' . $q->re
+set ] ), # here's where I changed the concantation.
                $q->td( [ $q->font ({-face=>'arial', -size=>'+1'}, $q-
+>b('Output:'))]),
                $q->td( { -bgcolor=>'#cccccc' }, [ "display" ]),

            ])
        ),
    $q->end_form,
    $q->end_html;

Not sure if you only print out a single table cell with out anything else if it behaves differently??
