okay, well, your code is requestin the db for data the vbulletin main array already contains, so, try this code and tell me if it works:

PHP Code:

if ($vbulletin->userinfo[field6] == 'Yes' AND $vbulletin->userinfo['usergroupid'] =='2')
{
    $userdata->set('usergroupid', 10);
}
elseif ($vbulletin->userinfo[field6] == 'No' AND $vbulletin->userinfo['usergroupid'] =='10')
{
    $userdata->set('usergroupid', 2);
} 


by the way, where did you found this $userdata->set() function? this seems to be a new trick for me
