So i use loadClip function to load different .swf in main main swf
also i use xml file to build a menu in flash.
All of this works here:
http://78.90.42.244/itpbg/flash/main.swf
but when i use swfobject by this way:

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

<script type="text/javascript">
swfobject.embedSWF("flash/main.swf", "page_body", "800", "770", "9.0.0", "expressInstall.swf");
</script>
and

<div id="page_body">
<h1>Alternative content</h1>
<p><a href="http://www.adobe.com/go/getflashplayer">
<img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" />
</a></p>
</div>

the flash doesn't work the loaded swf and xml menu doesn't appeared

So any ideas why is this ?

My pc was shut down.

So i fix the problem - it's not swfobject related. Just:

"Concerning the loading of external data with the loadClip method, the Flash help (the one that shows up when you press F1 in Flash) states that "A relative path must be relative to the SWF file..." I found out that this is NOT the case. The path to the external file must be relative to the HTML file inside which your main SWF file is embedded!"

This shorted my life with few hours :D
