Attaching MC to _level1

Hi Guys,

I want to attach my movie clip to _level1
my code is as follows:

var a:Number = Stage.width/2;
var b:Number = Stage.height/2;

function attach (){
this.attachMovie(“hitarea”,“hitarea_mc”,10,{_x:a,_y:b});

}

hit_mc.onRelease = function(){
attach();
}

I thought _level1.attachMovie(etc,etc); would work … but it doesnt. Can anyone point me in the right way? Thanks!!:pirate3:
