So you don't want to have the code displayed to members that are not in usergroup ID 18, 19 or 20?

Then use this code

PHP Code:

if (!is_member_of($bbuserinfo, 18) AND !is_member_of($bbuserinfo, 19) AND !is_member_of($bbuserinfo, 20))
{
    //Code I don't want paying members to see
}

NOT (x OR y OR z) = (NOT x) AND (NOT y) AND (NOT z) => DeMorgan's Theorems
