[F8-AS2] Flash over HTML

I know this has been covered on this site before, but the tutorials and explanations that I found here (and elsewhere) have yet been able to help me in solving this problem. I am trying to make a simple flash header drop-down menu, drop down over HTML content.

I have referred to the following for help, but am still having problems:

I am using swfobject.js and here is the embed code that I use:


<script type="text/javascript" src="swfobject.js"></script>         

     <div id="flashcontent">
       Please download the newest version of flash player <a href="http://www.adobe.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash">here</a>

     <script type="text/javascript">
        var so = new SWFObject("whatever.swf", "someTitleHere", "900", "225", "7", "#FFFFFF");
        **so.addParam("wmode", "transparent");**

I have also tried it with adding, so.addParam(“z-index”, “someNumber”);, but that hasn’t worked at all.

I have tried all of, and all combinations of, the following CSS trying to get something to work with no luck:

position: absolute; **// attempting to anchor it at the top where it is embeded**
background: transparent; **// attempting to put a transparency on the <div> itself**
z-index: 1; **//attempting to set the z-index above that of the HTML content**

position: relative; **//attempting to anchor it right below the flash where it is embeded**
top: -85px; **// attempting to nestle the HTML page right up under the flash**
z-index: 0; **// attempting to set the z-index below that of the flash**

Could anyone please explain what I may be missing/doing wrong. Or if there are any known issues or circumstances (i.e. being inside of a table or something) in which this will not work, that may be preventing me from doing this?

Much thanks in advance for any help.
