Css not working properly in IE

Hello

I am trying to align flash object to a header in an html page. I am publishing flash as 100% width and 100% height. Now everything is working fine in Firefox but when I try the html page in IE the flash object doesnt show up.

Any idea why this might be happening. the html code is given as under


 
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>main</title>
<script language="javascript">AC_FL_RunContent = 0;</script>
<script src="AC_RunActiveContent.js" language="javascript"></script>
<style>
 body {
  padding:0;
  margin:0;
  text-align:center;
  }
 #wrapper {
  width:860px;
  margin:0 auto;
  }
 #header {
  text-align:left;
  }
 #flash {
text-align:left;
  }
</style>
</head>
<body bgcolor="#ffffff">

  alert("This page requires AC_RunActiveContent.js.");
 } else {
