MC gtp frame in root timeline

After searching page after page in the forums I can’t find a solution that works for me. I want an externally loaded MC[L(1)] to go to and play “Scene 1, 16” of my root timeline upon closing it.
Here is the code I placed on my MC’s “close” button:

on (release) {
_root.gotoAndPlay("Scene 1", 16);
unloadMovieNum(1);
}

But for some reason it is not working, I tried with parent. but it did not work as well. After my MC closes, the frame on the root. timeline doesn’t switch as it is supposed to. I’ll appreciate any guidance. thanks a lot.
