How to get adsense on right side of first post ?

How to add adsense square box 336 x 280 pixel size on right side of first post ?

I am using this code.

Code:

<!-- message -->
<if condition="!is_member_of($bbuserinfo, 2, 5, 6)">
<if condition="(($post[postcount] % $vboptions[maxposts] == 1)) and ($show['guest'])">
<span style="margin: 2px; float: right; width: 336px; height: 280px;"> 
<script type="text/javascript"><!--
google_ad_client = "pub-121212121212121212";
/* Style 2 - Box 1 */
google_ad_slot = "121212121212";
google_ad_width = 336;
google_ad_height = 280;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
</span>
</if>
</if>
<div id="post_message_$post[postid]">
<!-- google_ad_section_start -->
$post[message]</div>
<!-- google_ad_section_end -->
<!-- / message -->

I am getting following results (attached image).
My quote box is messed up.

Please help me fix this ASAP.

Quote box in above image appears only when there are couple of lines in first post, if there are many lines in first post quote box is aligned properly.

What should be done ?

</div>
</if>
$post[message] </div>
<!-- / message --><br />

thank you for the reply, I am unable to understand your code above, can you kindly include the code above in my first post and re-post the same with required changes ?

Did you meant to use <div> tag instead of <span> ?
and
move <div id="post_message_$post[postid]"> before <if> condition ?

Yes, I mean div-tags

If you take a look at our forum you will see, that the code work very well. Only guests can see the code in the thread.
