Where is the referrerid?

[Mr Chad]

I want to create a second ID for myspace account numbers... I can set it all up but cant grab the number from the link... So far i put this in the global.php to see if it would work...

if ($vbulletin->GPC['myspaceid'] AND !$vbulletin->GPC[COOKIE_PREFIX . 'myspaceid'])
{
        vbsetcookie('myspaceid', $myspaceid);
}

The referrerid one is this:

if ($vbulletin->GPC['referrerid'] AND !$vbulletin->GPC[COOKIE_PREFIX . 'referrerid'] AND !$vbulletin->userinfo['userid'] AND $vbulletin->options['usereferrer'])
{
    if ($referrerid = verify_id('user', $vbulletin->GPC['referrerid'], 0))
    {
        vbsetcookie('referrerid', $referrerid);
    }
}

Am i missing a file, I made a $myspaceid under the $referrerid in the global.php still cant get it to work right.

anyone?
