Drag and hittest a movieclip to multiple movieclips

Hi!
I'm trying to find out a way to solve a problem with a drag and hittest exercise in AS2. What I want to do is the following: I have a movieclip (a ball) which I can drag to 9 possible movieclips (squares), so that ball has to hit only nine times with the different squares. And after the ball hits with a square, I want to make it available to hit with the rest of the squares and once a square is hitten it must be disabled.
I'm using thw following code to tha drag and hit test:

Code:

---

onClipEvent (load) {
        hor = this._x;
        ver = this._y;

        this.onRollOver = function() {
                this._alpha = 100;
        };
        this.onRollOut = function() {
                this._alpha = 50;
        };
        this.onPress = function() {
                this.getNextHighestDepth();
                this._alpha = 100;
                this.startDrag();
        };
        this.onRelease = function() {
                this.stopDrag();
                for (var i = 0; i<9; i++) {
                        if (this.hitTest(["sqaure"+i])) {
                                this.slideTo(["square"+i]._x,["square"+i]._y,0.5);

                        } else {
                                this.slideTo(hor,ver,0.5);
                                this._alpha = 50;
                        }
                       
                }
                this.onReleaseOutside = function() {
                        this.stopDrag();
                        this.slideTo(hor,ver,0.5);
                        this._alpha = 85;
                };
        };
}
