How to send flash swf object behind other asp.net controls?

Yes, I have already tried wmode="transparent" but it didn't work.

The codes I'm using at the moment:

<style type="text/css">

   #flash

   position: relative;

   z-index: 0;

   #popup

   position: relative;

   z-index: 100;

</style>

<script language="javascript">

   if (AC_FL_RunContent == 0) {

  alert("This page requires AC_RunActiveContent.js.");

  } else {

  AC_FL_RunContent('codebase', 'http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0', 'width', '1013', 'height', '1300', 'id', 'maintopVIC', 'align', 'middle', 'src', 'maintopVIC', 'quality', 'best', 'bgcolor', '#ffffff', 'name', 'XXX', 'allowscriptaccess', 'sameDomain', 'allowfullscreen', 'false', 'pluginspage', 'http://www.macromedia.com/go/getflashplayer', 'movie', 'XXX'); //end AC code

   </script>

<div id="flash">

   <object classid="clsid:XXXXXXX .... " codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0"

   width="1013" height="1300" id="XXX" align="middle">

   <param name="allowScriptAccess" value="sameDomain" />

   <param name="allowFullScreen" value="false" />

   <param name="movie" value="XXX.swf" />

   <param name="quality" value="best" />

   <param name="bgcolor" value="#ffffff" />

   <param name="wmode" value="transparent">

   <embed src="XXX.swf" quality="best" bgcolor="#ffffff" width="1013" height="1300"

   name="maintopVIC" align="middle" allowscriptaccess="sameDomain" allowfullscreen="false"

   wmode="transparent" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />

   </object>

</div>

Thank you.
