All variables which you defined in the settings are available through

PHP Code:

$vbulletin->options['oftw_can_view'] 


the code snippet you're looking for is:

PHP Code:

if (!is_member_of($vbulletin->userinfo, $vbulletin->options['oftw_can_view'])) {
    print_no_permission();
} 


If you want to improve your setting so you can define more usergroups separated through commata, use this instead:

PHP Code:

if (!(is_member_of($vbulletin->userinfo, explode(',',$vbulletin->options['oftw_can_view'])))) {
    print_no_permission();    
} 


Also make sure to position this code after global.php inclusion.
