In your template "MEMBERINFO", make sure that you followed the directions in the mod exactly. Do you see text that matches this::
Code:
<if condition="$userinfo[field10]">
<tr>
<td><a href="#" onclick="return imwindow('gt', '$userinfo[userid]', 450, 200)"><img src="images/misc/im_gt.gif" border="0"></a></td>
<td><a href="#" onclick="return imwindow('gt', '$userinfo[userid]', 450, 200)">$userinfo[field10]</a></td>
</tr>
</if>
Make sure that you are using your correct profile field, NOT mine, which happened to be "field10" (unless yours is field10, as well). There are
two places in this code where you must modify this, and I think that's your problem. :P
