Hi everybody,
I need help...
My problem is: insert in memberlist an image that is different for usergroup.
I try to use this code without result:

<if condition="is_member_of($userinfo[usergroupid], 16)">
<div><img src="/images/icons/abc.gif" border="0" alt="" /></a></div>
</if>

<if condition="is_member_of($userinfo[usergroupid], 13)">
<div><img src="/images/icons/def.gif" border="0" alt="" /></a></div>
</if>

the same result with

  <if condition="is_member_of($post, 16)">
<div><img src="/images/icons/abc.gif" border="0" alt="" /></a></div>
</if>

  <if condition="is_member_of($post, 13)">
<div><img src="/images/icons/def.gif" border="0" alt="" /></a></div>
</if>

Someone can help me?
