Button controlling Content of a MC

1

Here goes, I have a button inside of a MC inside a MC, My question is, if a button could controll the content of another MC.

Simplified (I hope):

  1. User clicks the button inside the MC inside the MC.

  2. On click, the content of another MC inside the same Flash file changes accordingly.

Hope that is partially understandible,

Pre-Thank you,
