Can't get AC_FL_RunContent to get swf from other directories

Okay i want to put the same swf banner on all of my pages. I have lots of sub directories, which will end up going 2 levels deep from the root. My problem is that I cannot get adobe’s active content runner script to pull the swf file that is in the root directory for pages that are 2 levels below it.

This works:


<script type="text/javascript">  
	
    		AC_FL_RunContent(  
  			'movie', '../sub_banner',  
 			'width','772',  
   			'height','99',
			'wmode','transparent'
                );  
			
</script>  

This does not work:


<script type="text/javascript">  
	
    		AC_FL_RunContent(  
  			'movie', '../../sub_banner',  
 			'width','772',  
   			'height','99',
			'wmode','transparent'
                );  
			
</script>  

Any ideas on how I can get this to work?
