what you are doing there is first load the sound file, and then close the window that is trying to load the file, so the window never gets the chance to play the sound..
if i\'ve got this right you have a popup window with these radiobuttons, then try something like onClick=\"openr.location.href=\'file.wmv\';window.close()\"
that might not be the best solution but was the first to come to my mind...
hope it helps...
