Button in movieclip not working

I have a button within a movie clip that I want to use to move to the next scene on the main timeline but I can’t get it to work. The stop all sounds works, but the goto does not.

[AS]
on (release) {
stopAllSounds();
_root.gotoAndPlay(“Scene 4”, 1);
}
[/AS]

Any suggestions? I trawled through this board’s archives and from what i found, it should work.

Incidentally, what is the best, cleanest and simplest way to stop a movie clip playing at a given frame? Can you simply use:

_root.MovieClip.stop ();

Cheers
