How do I Remove ad after first postbit

[ski diva]

Just when I thought all was well.... I added that code to the end, and ended up with no adsense ads after the first postbit on any of my other forums, PLUS an empty space for an ad after each post in a thread. So I took it out. Now I'm not getting adsense at all on my other forums (though I am getting the space for it after the first post in a thread, and I'm no longer getting the empty space after each post), and there's no targeted ad (or even adsense) to on my "Ask The Expert" forum at all. (God, I hope this is clear!). I have no idea what could possibly have gone wrong. Help, please!

Here's my code:

</div>
$spacer_close
</if>
<!-- / post #$post[postid] -->
<if condition="$post[postcount] % $vboptions[maxposts] == 1">
<if condition="$forum[forumid] != 26">
$spacer_open
<div style="padding:0px 0px $stylevar[cellpadding]px 0px">

<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"><!--
<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"

</script>
</td>
</tr>
</table>


</div>
$spacer_close
