Passing instructions from button in MC to another symbol

I have button Alpha. When clicked, it tells movie clip One to move to y coordinate zero. This actionscript works fine.

But when I place the button inside movie clip Beta, no longer can it tell movie clip One to move.

I keep reading references to relative paths and such, but i can’t seem to make it work. I’ve attached the MX 2004 file to show what’s (not) going on.

Can anyone help? thanks!
