Condition based on how many posts in showthread?

[punchbowl]

Yeah it doesn't seem to work here's what I have:

<if condition="$show['guest']">
<table width="$stylevar[outertablewidth]" border="0" cellpadding="0" cellspacing="0" align="center">
	<tr>

	<td width="140" valign="top" class="page" style="padding: $stylevar[cellpadding]px;"><if condition="THIS_SCRIPT == 'forumdisplay' AND $show['guest']">
<div align="center">AD HERE</div><br />
</if>
<div align="center">AD HERE</div>
<if condition="$show['guest'] AND THIS_SCRIPT == 'showthread' AND $thread['replycount'] > 5">this ad never shows</if>
	<td valign="top">
	</if>
<!-- content table -->

Another question are the $show['guest'] conditions in the second two conditions obsolete as they are wrapped in a $show['guest'] condition anyway?

I know I could be playing around with this but it's a live board and they'd go hysterical if I started playing around now.
