how to show flash object below all html controls/elements

I faced problem that draggable div or dropdown style menu can't show over Flash Object(.swf). finally I solved the problem as follows

I used the below code to embed flash object

<script type="text/javascript">

          AC_FL_RunContent('codebase', 'http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,28,0', 'width', '628', 'height', '392', 'src', 'venezuela_banner', 'quality', 'high', 'pluginspage', 'http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash', 'movie', 'venezuela_banner'); //end AC code

      </script>

      <noscript>

          <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,28,0"

              width="628" height="392">

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

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

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

              <embed src="venezuela_banner.swf" wmode="transparent" quality="high" pluginspage="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash"

                  type="application/x-shockwave-flash" width="628" height="392"></embed>

          </object>

      </noscript>

 AC_FL_RunContent was defined in a javascript file AC_RunActiveContent.js.
But this doesn't serve the problem.
finally I use the code below and it is sovled

<object type="application/x-shockwave-flash" data="venezuela_banner.swf" width="628" height="392"> 

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

<param name="allowfullscreen" value="true" /> 

<param name="allowscriptaccess" value="always" /> 

<param name="flashvars" value="file" /> 

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

<embed width="628" height="392" src="venezuela_banner.swf" wmode="transparent" allowfullscreen="true" allowscriptaccess="always" type="application/x-shockwave-flash"></embed>

</object>
