Nextscene() function

Ok, i have flashmx2004 and love it. There are a few things that have been puzzling me for a while. I have a movie with multiple scenes, and i would like a button to be able to go foward one scene or go back one scene. I have success when i put the button on the parent level and use the A.S. :

on (release) {
	nextScene();

}

But if i try to put this same code on a differant level like within a movie clip or even a movie clip that has a button. Or any level other than root, the code will not work. I have tried using :

on (release) {
	_root.nextScene();

}

But no luck there.
Any ideas?

thanks,
Nimbus
