Disable Ads for Users in a "Premium" Secondary Group

[Boss-Hog]

All,

I found the below snippet of code works to disable advertisements for users that are in specified primary usergroup, but all of my premium users maintain their normal usergroup and have a secondary premium usergroup to denote if they subscribe or not. As a result, what is the equivalent of the below snippet of code for secondary usergroups instead of primary usergroups? Thanks in advance.

<if condition="$bbuserinfo['usergroupid'] != X"> </if>

where X is the premium usergroup ID
