Scenes

hi, I have a button within a MC and when clicked i want to go to another scene,
I have tried

_root.gotoAndStop(“MyScene”,1);
gotoAndStop(“MyScene”,1);
gotoAndPlay(“MyScene”,1);
and
_root.gotoAndPlay(“MyScene”,1);

but it doesn’t work. all element have instance names and a trace(); on the button confirms it has been clicked, but it just wont switch to the new scene, any ideas?
