Help connecting buttons in sights

hi.
I’m making my first flash sight, but i have a problem. I want the menue buttons to go and play a frame within another movie clip. But i dont know HOW!

I tried this on one of the buttons:

on(release){
gotoAndStop(_root.object1.object2, 2);
}

But it sais:
“Scene name must be quoted string”

Please help
