Flash movie på website

Kan I fortælle mig hvorfor den første ikke fungerer helt efter hensigten, mens  den første virker fint?

        <script type="text/javascript">
            var so = new SWFObject("fileUpload.swf", "fileUpload", "700", "100", "8", "#336699");
            so.addParam("movie", "fileUpload.swf");
            so.addParam("quality", "high");
            so.addParam("wmode", "transparent");
            so.addParam("uploadPage", "Upload.axd");
            so.addParam("completeFunction", "UploadComplete()");
            so.write("flashcontent");
      </script>
