I suck at Z index /positing elements …help!!!

div.frontpageoverlay{
	position:absolute;
	top:650px;
	margin-left:800px;
	z-index:1;
}

I have this set up for the “email for media” widget on my homepage but can’t get it to stay exactly put… this is the code for the homepage

<div class="frontpageoverlay"><object type="application/x-shockwave-flash" height="80" width="400" id="TSWidget13736" data="https://cdn.topspin.net/widgets/email2/swf/TSEmailMediaWidget.swf?timestamp=1265820085" bgColor="#000000"> <param value="always" name="allowScriptAccess" /> <param name="allowfullscreen" value="true" /> <param name="quality" value="high" /> <param name="movie" value="https://cdn.topspin.net/widgets/email2/swf/TSEmailMediaWidget.swf?timestamp=1265820085" /> <param name="flashvars" value="widget_id=https://cdn.topspin.net/api/v1/artist/1515/email_for_media/13736?timestamp=1265820085&theme=black&highlightColor=0x00A1FF" /></object></div>
