Code:
<if condition="$post['field6']">
<div id="gamertagmenu_$post[postid]"><b><u>$post[field6]</u></b>
<script type="text/javascript"> vbmenu_register("gamertagmenu_$post[postid]", true); </script>
</div>
<div class="vbmenu_popup" id="gamertagmenu_$post[postid]_menu" style="display:none"><iframe src="http://gamercard.xbox.com/$post[field6].card" scrolling="no" frameBorder="0" height="140" width="204">$post[field6]</iframe> </div>
</if>
That "should" do it.
If not, try this
Code:
<if condition="$post['field6']">
<div id="gamertagmenu_$post[postid]"><b><u>$post[field6]</u></b>
<script type="text/javascript"> vbmenu_register("gamertagmenu_$post[postid]", true); </script>
</div>
<div class="vbmenu_popup" id="gamertagmenu_$post[postid]_menu" style="display:none"><iframe src="http://gamercard.xbox.com/$post[field6].card" scrolling="no" frameBorder="0" height="140" width="204"></iframe> </div>
</if>
