Move banner to specific spot

Alright, alot of you might not get through this because it involves myspace, but I need your help with positioning a banner.

The myspace is myspace.com/duanemanns

As you can see there is a banner that needs to be positioned in the center, below the addds and above the music player etc. Here is the code.

<style type="text/css">

body{
background-position:top center;margin-top: 300;}

div.topbanner {
top: 0;
left: 49%;
margin-left: -230px;
width: 700px;
height: 457px;
position: absolute;
}
</style>

<div class="topbanner">
<IMG SRC="http://www.aslan-studios.com/david/Duane's%20MySpace/masthead.jpg" border="0">
</div>


<style type="text/css">

form>img#googleTLogo
{
    background-image:url(http://x.myspace.com/images/powered_by_google_white.png);
    background-repeat: no-repeat;
}

#googleTLogo
{
    vertical-align:bottom;
    width:120px;
    height:30px;
    filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src='http://x.myspace.com/images/powered_by_google_white.png', sizingMethod='image');
}


</style>

I’ve googled for a while, used Mike D’s tutorial, even copied the code I used on another mySpace before but for some reason it just isn’t working. Thanks again for any help.
