How to show ads in first post at the end of message?

[PAKIDIL]

Hello,

I am trying to show ads in my first post at the end of the message just above the signature but It's not working .

I am trying this :



Code using :

<if condition="THIS_SCRIPT != 'register' AND !in_array($GLOBALS['forumid'], array(x,x,x,x))">
<if condition="is_member_of($vbulletin->userinfo, x,x,x)"><script type="text/javascript"><!--
google_ad_client = "xxxx";
/* 728x90 bottom ad */
google_ad_slot = "dxxds";
google_ad_width = 728;
google_ad_height = 90;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
</if>
</if>

Can anyone suggest me please how to make it work?
