Check this part out:
PHP Code:
if ($post['posts'] > 10 && $post['fieldx']) {
$post['username'] = '<table style=filter:glow(color="' . $post[fieldx] . ', strength=2")>' . $post[username] . '</table>';
}
See those <table> tags..I personally don't recall the username being inbetween the <table> tags, so it's probably not needed.
Try replacing the <table> and </table> with a <td> and </td> tag, then with some tweaking around you should be able to remove the space maybe..
