problem with path - parent? root? level?

[wywalk]

I'm having trouble determining a path. I have a movie clip (playSlideshow) that's supposed to control the starting and stopping of a slideshow. It works perfectly when I test it as a standalone, but when I load it onto Level1 of the main movie, it stops working.

The movie clip (playSlideshow) contains two frames:

1st frame:
on (release) {
this.nextFrame();
}
on (release) {
_parent.peelProperty.startAutoPlay(3);
}
2nd frame:
on (release) {
this.prevFrame();
}
on (release) {
_parent.peelProperty.stopAutoPlay();
}

The movie clip lives on the same timeline as the instance (peelProperty) that it's supposed to start and stop. Since it works as a standalone, I'm guessing that "_parent" is the problem - what should it be?

Here it is as a standalone:

Here it is on level1 - click "one bedroom" to load it:

Thanks,
