conditionals about groups

[vauge]

Why does

PHP Code:

<if condition="!is_member_of($usergroupid,38) AND !is_member_of($usergroupid,39) AND !is_member_of($usergroupid,39)">Display something here</if> 


or this

PHP Code:

<if condition="!is_member_of($usergroupid,38,39,40)">Display something here</if> 


NOT work?

Secondary groups - thanks!

I want everyone but groups 38,39,and 40 to see it.
