Passing PHP variable to Flash Players using FlashVars

Im testing out a script, whicgh seems to work fine, except for the fact that when I try loading a URL which has a comma in it, the file does not load in the player.

<param name="FlashVars" value="playerID=1&amp;soundFile=http://domain.com/test,file.mp3">

Code (markup):

I need a solution that will play the file without having to change the URL as the file is hosted externally.

 

It works fine for me. Make sure you have

in your embed code.
