Not targeting button correctly

Hey guys i have a movieclip in a scene that i want to target with the actionscript in the first frame. The movie clip is called up_btn and im trying to target a label called “over” within it.

So here is my code i know im doing something wrong i just dont know what.

up_btn.rollOver
up_btn.gotoAndPlay(“over”);

It suppose to seens something like this:

up_btn.onRollOver = function()
{
  this.gotoAndPlay("over");
}

I thought for sure that would work would the fact that i also have a couple of other button states conflict with that like:

up_btn2.onPress = function() {
myInterval = setInterval(movedragger2, 18, -1);
};

would any of those settings interfere with the flash?

Got it this was apparantly what its supposed to say:

up_btn.onRollOver = function(){
up_btn.gotoAndPlay(“over”);
}
