Sound problem

I am making a mp3 player but it seems to be the rules that every site needs a mp3 player. Ive made one before and was pretty straight forward but this time it seems not to work when I preload it

on (release){

sound = new Sound();
sound.loadSound(“sound3.mp3”,false);
sound.start();
}
thats the code Im using it should work right? does any one know wha tmight be the prob here?
