Have you tried using their simple example with just

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

<div id="flashcontent">
  This text is replaced by the Flash movie.
</div>

<script type="text/javascript">
   var so = new SWFObject("movie.swf", "mymovie", "400", "200", "8", "#336699");
   so.write("flashcontent");
</script>

of course you will need to replace "swfobject.js" with the correct path and "movie.swf" with appropriate path & file name.  Check the documentation for more info on other parameters.
