Menu Troubles

I have a problem with my menu that I made. It has a quality button that looks like this at 100%:

And this zoomed in:

I have every other button fine, but I can’t get the quality button to work.
It’s all a movie clip, and I’ve managed to do this before. I have 3 frames. The AS in frame 1 is:
_root._quality = “High”
stop();
frame 2:
_root._quality = “Medium”;
stop();
frame 3:
_root._quality = “Low”;
stop();

I need 3 frames, so putting them in one frame is not an option.
The only time it works is when I test scene inside the movie clip.
I need to make it so that I don’t need to break it apart, because that doesnt’ work.
The button in frame one contains the following AS is as follows:
on (release) {
gotoAndStop(2);
}
frame 2:
on (release) {
gotoAndStop(3);
}
frame 3:
on (release) {
gotoAndStop(1);
}

For some reason, it doesn’t work when I don’t test scene inside the movie clip.
Suggestions?
This is in Flash MX, by the way.
