Is this wrong ? >> attachSound in an array

any thing wierd with this array script ?

its not working.

it is on frame one of root. and so is nextBtn.

nextBtn.onRelease = function() {
filename =
[“clips/apollo13.wav”,“clips/cosmicdebris.wav”,“clips/earth.wav”,“clips/prez4.wav”,“clips/smallstep.wav”,“clips/houston2.wav”,“clips/spaceship.wav”,“clips/culture.wav”,“clips/cassini.wav”,“clips/blackhole.wav”,“clips/cosmic114dings.wav”,“clips/go-flight2.wav”,“clips/H-rogerout2.wav”,“clips/OKsoundsfine2.wav”,“clips/pixonTV.wav”,“clips/liftoff2.wav”];
i = filename.length;
k = Math.floor(Math.random()*i);

mysound = new Sound();
mysound.attachSound(filename[k]);
mysound.start();}
