you need to get the userid variable some how. Opserty and I gave two different codes for linking to it such as using $bbuserinfo[userid] and <?php echo $vbulletin->userinfo['userid'] ?>

If you manage to get that, then when say user 5 is logged in and the click your link it will take them to user5's profile

We understand what you are doing but you need the users vBulletin userid. I gave the link you'd need. The rest is up to you to work out, this isn't really vBulletin related, it is to do with the integration (if you have done any...). You need the users vBulletin userid number.

In normal vBulletin you can access that by using these two variables:
I think your issue maybe resides with the Ladder script not vBulletin...
