Simple code not working

Hello, is there anything wrong with this code…

PlayButton.onRelease = function(){
PlayButton.gotoAndStop(2);
stopAllSounds();
Radio01.gotoAndPlay(“Play”);
};
StopButton.onRelease = function(){
_root.PlayButton.gotoAndStop(2);
stopAllSounds();
};

I have that code on frame 5 of my project in an actions layer.
Then I have on a different layer on the same frame (5) the two movieClips
that have the instance names of PlayButton & StopButton.

I can´t figure out why it isnt working. Any ideas?

Thanks.
