Can you test dragOver in drag and drop?

I’ve been trying lots of different options to make this work, but nothing seems to work. I have a drag and drop interaction and I want the possible hit area (chart_mc.hit1) to change alpha when the user drags the selection (drag_mc) over it to indicate that they’re in the drop area…

Here’s the code I’m using and the .fla is attached…

var droppedIn = false;
drag_mc.onRelease = function() {
    trace("this._droptarget "+this._droptarget);
    this._x = 106;
    this._y = 200;
    droppedIn = true;
    this.gotoAndStop(4);
    stopDrag();
};
drag_mc.onPress = function() {
    startDrag(this, true);
};
drag_mc.onRollOut = function() {
    chart_mc.hit1._alpha = 15;
    if (droppedIn == false) {
        this.gotoAndStop(1);
    } else {
        this.gotoAndStop(3);
    }
};
drag_mc.onRollOver = function() {
    if (droppedIn == false) {
        this.gotoAndStop(2);
    } else {
        this.gotoAndStop(4);
    }
};
drag_mc.onDragOver = function(){    
    trace("drag_mc.onDragOver "+this._droptarget);
    if (this._droptarget == " /chart_mc/hit1") {
        chart_mc.hit1._alpha = 60;
    }
}
drag_mc.onDragOut = function(){    
    trace("drag_mc.onDragOut "+this._droptarget);
        chart_mc.hit1._alpha = 15;
}
stop();

Thanks for any help!!
