You can do something like this...

PHP Code:

$allowed_usergroups = array(1,2,3,4);

if (!in_array($vbulletin->userinfo["usergroupid"], $allowed_usergroups)) {

     print_no_permission();  
     
    } 


Place the usergroups you want to allow in the array (separated by commas, of course). If the user is not in that group it will give the no permission message.
