code help

[Mythotical]

Ok I managed to get alot of this ported hack working, but when I go into my admincp->users->my admin account->Add Linked Accounts to (user)

I then enter the userid to link to, a list of all accounts show up, that doesn't bother me, I click on (Link) which then is supposed to link the 2 accounts together but instead it does nothing, its supposed to give a message stating the accounts were linked.

Any ideas what could be wrong?

I am providing the code that I had to use and the qas.php file. If you wish to look over it and provide better feedback, please do. It suggested I check that 'u' is being converted to 'userid' but I have no clue what I'm looking for when it comes to that.

global.php add in code:

# Quick Account Switch v1.2
unset($account_master); // empty markup for good measure
if ($bbuserinfo['userid']) // verify we are logged on
{
	if ($bbuserinfo['qas']) // slave or master account defined?
	{
		$qas = unserialize($bbuserinfo['qas']);
		foreach ($qas as $qas_acct => $qas_acct_value)
		{
			if ('m'==$qas_acct_value['type']) // we are a master account to this slave account
			{
				$account_master .= "<tr><td class=\"vbmenu_option\"><a href=\"login.php?do=switch&id=$qas_acct_value[userid]\">" . base64_decode($qas_acct_value['username']) ."</a></td></tr>";
			}
			else // we are a slave account to this master account
			{
				$qasmast=fetch_userinfo($qas_acct_value['userid'], 0); // get master account's QAS details
				// add master account at the top of the list
				$account_master .= "<tr><td class=\"vbmenu_option\"><a href=\"login.php?do=switch&id=$qasmast[userid]\">$qasmast[username]</a></td></tr>";
				// add all slaves except myself
				$qas2 = unserialize($qasmast['qas']);
				foreach ($qas2 as $qas_acct2 => $qas_acct_value2)
				{
					if ($qas_acct_value2['userid'] != $bbuserinfo['userid']) // if I'm not this slave
					{
						$account_master .= "<tr><td class=\"vbmenu_option\"><a href=\"login.php?do=switch&id=$qas_acct_value2[userid]\">" . base64_decode($qas_acct_value2['username']) . "</a></td></tr>";
					}
				}
			}
		}
	}

Any help much appreciated and Marco, if you can help that would be great.
