How do I Remove ad after first postbit

[ski diva]

Yep. The forum ID is "Ask The Expert," so I entered the following:
Ask_The_Expert

Here's the code I used:

</div>
$spacer_close
</if>
<!-- / post #$post[postid] -->
<if condition="$post[postcount] % $vboptions[maxposts] == 1">

$spacer_open
<div style="padding:0px 0px $stylevar[cellpadding]px 0px">

<if condition="$forum[forumid] != Ask_The_Expert">
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<tr>
<td class="thead" align="left">Sponsored Links</td>
</tr>
<tr>
<td class="alt1" align="center">
<script type="text/javascript"><!--
google_ad_client = "NUMBER HERE";
google_ad_width = 728;
google_ad_height = 90;
google_ad_format = "728x90_as";
google_ad_type = "text";
google_ad_channel ="";
google_color_border = "FFFFFF";
google_color_bg = "F4F4FF";
google_color_link = "4B548B";
google_color_text = "000000";
google_color_url = "4B548B";
//--></script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
</td>
</tr>
</table>
</if>

</div>
$spacer_close

</if>

So what am I doing wrong?
