Flash player in a sidebar

I’ve searched around in the forums but I can’t quite find the solution for my problem. I am using a 3-column template and I would like to be right sidebar to be a flash music player that I designed.

The template includes a “sidebar2.php” with the following code:
<div class=”right_side”>

<object classid=”clsid:D27CDB6E-AE6D-11cf-96B8-444553540000″ codebase=”http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0&#8243; width=”204″ height=”551″>

<param name=”movie” value=”rightside.swf”>

<param name=”quality” value=”high”>

<embed src=”rightside.swf” quality=”high” pluginspage=”http://www.macromedia.com/go/getflashplayer&#8221; type=”application/x-shockwave-flash” width=”204″ height=”551″>
</embed>

</object>

</div>

When I view the page, it seems to be loading the Flash object (IE warns about ActiveX content, you have to click to activate content), but there is only a white box with the dimensions of the object. Is the Flash being obscured by something? Am I embedding it incorrectly? Do I need a plug-in installed to run the Flash? Any clues will be appreciated.
