Swf not playing from directory

I have a swf and it’s XML file in the same directory “swfs” on my server. When I set my html code up I set the value as such

<param name=“movie” value="/swfs/xml_ticker_what.swf" />

the web page in question: http://dev-bs.virtualhorizons.com/what.asp?isOn=4 is outside the swfs directory.

Is there some rule about swfs and the web page they are on being in the same directory?
