loading movie clips into other movie clips

[nrvus19]

I have a main timeline with 2 loaded movie clips loaded.

Main>
MC1
MC2


On the main timeline i have a button which when pressed loads information into MC1.

From MC1 I have button which I would like to load contect into MC2.

What is the correct way to make this happen?
Thank you.

Should just be:

buttonone.movieclip2.loadMovie("whatever.swf");

Unless I'm misunderstanding.
