How do I point to another movieclip?

I have two mc’s in the standard “Scene1”. And inside the first movieclip I have a button, wich I want to redirect me to frame #10 in “mc2” that is located in the root aswell. So I tried the following code, where “mc_kontakt” is the “mc2”. But nothing happens. what am I doing wrong?

on (release, releaseOutside){
