I broke the ACP attempting to get permissions - help

[Sawa Dee SohL]

For some unknown reason I'm not able to access Admin Permissions on my own website. I was attempting to make the changes in the config area - but I stumbled across adminfunctions.php - and thought it might be in there (why i'm not sure) - and made some changes to the following code, and now I've completely broke my ACP - can't even log into it, receiving this error: Parse error: syntax error, unexpected T_STRING

Can someone tell me what part of this code i messed up, and the correct way to put it so I can access my ACP? I'm user ID 1 - and if possible, can someone tell me where to access the config.php file - I can't seem to find it, and the end of the coding makes me think it's there, just hidden?

global $vbulletin, $_NAVPREFS;

	static $admin, $superadmins;

	if (!isset($_NAVPREFS))
	{
		$_NAVPREFS = preg_split('#,#', $vbulletin->userinfo['navprefs'], -1, PREG_SPLIT_NO_EMPTY);
	}

	if (!is_array($superadmins))
	{
		
              $superadmins = preg_split('#?s*,?s*#s', $vbulletin->$config['SpecialUsers']['superadministrators'], -1, PREG_SPLIT_NO_EMPTY);
	}

	$do = func_get_args();

	if ($vbulletin->userinfo['userid'] < 1)
	{
		// user is a guest - definitely not an administrator
		return false;
	}
	else if (!($vbulletin->userinfo['permissions']['adminpermissions'] & $vbulletin->bf_ugp_adminpermissions['cancontrolpanel']))
	{
		// user is not an administrator at all
		return false;
	}
	else if (in_array($vbulletin->userinfo['userid'], $superadmins))
	{
		// user is a super administrator (defined in config.php) so can do anything
		return true;
