Code Help?

[netsavy006]

Here is my current code for google adsense revenue sharing:

<if condition="$post[postcount] == 1">
<if condition="THIS_SCRIPT == 'showthread' AND ($post[postid] == $GLOBALS['qrfirstpostid'])">
<if condition="$show['spacer']">$spacer_open<div style="padding:0px 0px $stylevar[cellpadding]px 0px"></if>

<table cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" bordercolor=white width="100%" align="center">
<tr><td class="alt1" style="padding:0px">
<div class="smallfont" align="center">
                <script type="text/javascript"><!--
                google_ad_client = "$post[ad_client_id]";
                google_ad_width = 728;
                google_ad_height = 90;
                google_ad_format = "728x90_as";
                google_ad_channel ="$post[ad_channel]";
                google_color_border = "FFFFFF";
                google_color_bg = "FFFFFF";
                google_color_link = "000000";
                google_color_url = "666666";
                google_color_text = "333333";
                //--></script>
                <script type="text/javascript"
               src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
                </script>
</div></td></tr></table>

<if condition="$show['spacer']"></div>$spacer_close</if>
</if>
</if>
</center>
<br />

It is set to display after the first post on the forum but I'd like to change it to after the last post, just above the quick reply. How do I modify the code to do that?

Thanks in Advance,
Andy...
