Use of _root & _parent

1

Hi, I have this problem:
I have main timeline with many frames and layers, on frame 25 i have a movie clip named “buttons”, inside it there are 7layers, 3 for movie clips of buttons, 3 for invisible buttons and 1 for actions. I just want that buttons to appear slowly when mouse is over and hide slowly when mouse is down. It’s simple when i would have to do smth like this on main timeline. I just make:
–> on actions layer

_root.picture1.onEnterFrame = function() { 
if (mouse_over_picture1) { 
_root.picture1.nextFrame(); 
} else { 
_root.picture1.prevFrame(); 
} 
};

–> on invisible buttons

on (rollOver) { 
_root.mouse_over_picture1 = true; 
} on (rollOut) { 
_root.mouse_over_picture1 = fstartlse; 
} on (release){ 
getURL(" http://www.blablabla.com"); 
}

But it doesn’t work when it is in “buttons” movie clip, I suppose there’s smth about _root in the code, I’m not very familiar with AS so I could use your help and appreciate it very much. Thx :slight_smile:
