hitTest Problems :(

1

I know there is like a million post about this, and the tutorial are there. But I looked at the tutorial and I am having some problems with it. I also looked at the forms and no such luck. Ok what I have is a car (box) and when it goes over the wall it says you hit the wall. Anyways, i donte the tutorial and it doesnt seem to be working for me when i follow what it says for me to do :S Can someone please help me. Here is my code



onClipEvent (enterFrame) {
	if (Key.isDown(Key.UP)) {
		_root.box._rotation = 360;
		currentY = this._y;
		this._y = currentY - 15;
	} else if (Key.isDown(Key.DOWN)) {
		_root.box._rotation = 180;
		currentY = this._y;
		this._y = currentY + 15;
	}
	if (Key.isDown(Key.RIGHT)) {
		_root.box._rotation = 90;
		currentX = this._x;
		this._x = currentX + 15;
	} else if (Key.isDown(Key.LEFT)) {
		_root.box._rotation = 270;
		currentX = this._x;
		this._x = currentX - 15;
	}
	
	if ((Key.isDown(Key.UP)) && (Key.isDown(Key.RIGHT))) {
		_root.box._rotation = 45;
	}
	if ((Key.isDown(Key.RIGHT)) && (Key.isDown(Key.DOWN))) {
		_root.box._rotation = 135;
	}
	if ((Key.isDown(Key.DOWN)) && (Key.isDown(Key.LEFT))) {
		_root.box._rotation = 225;
	}
	if ((Key.isDown(Key.LEFT)) && (Key.isDown(Key.UP))){
		_root.box._rotation = 315;
	}

					hit = true; //make our hit variable true 
				} 
		} 
		if(hit) { //check out hit variable for a true or false collision detection 
			_root.text = "You Hit the WALL";
		} else {
		_root.text = "YOUR GOOD"; //do actions if they aren't touching

	//WALL this works
	  /* if (_root.box, hitTest(_root.wall.perimeter)) {
          _root.text = "Collision Detected";
    } else {
          _root.text = "No Collision";
    }*/

}

P.S I know there is a way to make the keyPress easy on me but I just want to do it this way LoL
