is_member_of Help please.

[lutics]

for some reason it doesn't want to work, it either shows for everyone or for no one. This is what I have tried so far.

PHP Code:

<if condition="is_member_of($user, "5, 6, 7")"><li>Staff License</li></if>
<if condition="is_member_of($user, 5, 6, 7)"><li>Staff License</li></if>
<if condition="is_member_of($bbuserinfo, 5, 6, 7)"><li>Staff License</li></if>
<if condition="is_member_of($vbulletin->userinfo, 5, 6, 7)"><li>Staff License</li></if>
<if condition="is_member_of($vbulletin->userinfo, array(5, 6, 7))"><li>Staff License</li></if> 


Nothing seems to work, this is my first time working with this function. I am editing the template. MEMBERSINFO aka profile.

Any help would be much appreciated
