Monkeys,
I'm trying to write a CGI that generates a dynamic table within another table also generated via CGI. I wrote a small test script to display what I want and it is posted below.
#!/usr/bin/perl -w
use strict;
use CGI;

my $q = new CGI;
print $q->header( -type => "text/html"),        
$q->start_html,
        $q->start_table(),
         $q->Tr(
                $q->td("Cell1"),
                $q->td("Cell2")
        ),
        $q->Tr(
                $q->td("Cell3"),
                $q->td(nested())
        ),
        $q->end_table,
$q->end_html;

sub nested
{
        $q->start_table(),
         $q->Tr(
                $q->td("Cell4"),
                $q->td("Cell5")
        ),
         $q->Tr(
                $q->td("Cell6"),
                $q->td("Cell7")
        ),
        $q->end_table,
}

This produces:
Cell1 Cell2
Cell3
Cell4 Cell5
Cell6 Cell7

When I attempt to change the code so the second table is created by a simple for loop like to the following: 
#!/usr/bin/perl -w
use strict;
use CGI;

my $q = new CGI;
print $q->header( -type => "text/html"),    
$q->start_html,
    $q->start_table(),
     $q->Tr(
        $q->td("Cell1"),
        $q->td("Cell2")
    ),
    $q->Tr(
        $q->td("Cell3"),
        $q->td(nested())
    ),
    $q->end_table,
$q->end_html;

sub nested
{
    $q->start_table();
    for (my $x = 4; $x < 8; $x++)
    {
        print $q->Tr(
            $q->td("cell ". $x),
            $q->td("cell ". $x+1)
        );
        $x++;
    }
        
    print $q->end_table;
}

I get: 
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
<HTML><HEAD><TITLE>Untitled Document</TITLE>
</HEAD><BODY><TABLE><TR><TD>Cell1</TD> <TD>Cell2</TD></TR><TR><TD>Cell
+3</TD> <TD>1</TD></TR></TABLE></BODY></HTML>

printed to the browser window. I'm curious as to what would cause this. I have a feeling I'm just overlooking something but as of yet I have not found said "thing."

As a side note: The code I am working on is Here but isn't having the same problem...instead the second table is printed first, and then the first table is printed beneath the second. If you're up for charity work you could take a look at that one as well. The code for it is posted Here
System Notes Just to make sure all needed info is given this is using 5.005_03 on Linux Redhat 6.2 and tested under Apache. If more info is needed I'll post it here if it is asked for
