refrencing sound from nested clips?

I have a question about referencing sound from a nested clip.

In my first frame on the root level I have this function:

function snd(iSnd:Sound):void {
var sndV:SoundChannel = iSnd.play(0, 0, sndTrans);
}

On the second frame of a nested clip I have this:


MovieClip(this.root).snd(MovieClip(this.root).loca tionSound);

I don't get any errors, but my sound doesn't play either. The function works fine when I am referencing it from the root level, but unfortunately I can't do that with this particular instance.

Any ideas?
