trying to show signature in custom page

[tipoboy]

hello i'm looking for a help trying to show users signatures the showgroups page. i've tried putting the code from the postbit in:

  <if condition="$post['signature']">
  <!-- sig -->
   <div>
    __________________<br />
    $post[signature]
   </div>
  <!-- / sig -->
  </if>

but it didnt work, on doing a search here i found an article with variables so tried

  <if condition="$post['signature']">
  <!-- sig -->
   <div>
    __________________<br />
    $bbuserinfo[signature]   
   </div>
  <!-- / sig -->
  </if>

that didnt work either, does anyone else have any suggestions??

thanks
- dave
