I don't use VBulletin, don't have the code, but i've got an idea.
PHP Code:
$normalc = ""; #Normal color
$highlightc = "red"; #The highlighted bar color
$output = "<table>\n";
for($pageloop=1;$pageloop<$totalpages;$pageloop++){
if($pageloop == $currentpage)
$output .= "<tr><td bgcolor=\"$highlightc\">$pageloop</td></tr>";
else
$output .= "<tr><td bgcolor=\"$normalc\">$pageloop</td></tr>";
}
$output .= "</table>";
echo $output;
I don't know if i used the right intergers, it may be like arrays or something: $vars["currentpage"];, i don't know cause i don't have the code...
