Whats wrong? please help!

Hi!

I need some help can some one tell my why this code don’t work:


onClipEvent (enterFrame) {
	if (Key.isDown(Key.DOWN)) {
		_y += 1;
	}
	if (Key.isDown(Key.UP)) {
		_y -= 1;
	}
	if (Key.isDown(Key.LEFT)) {
		_x -= 1;
	}
	if (Key.isDown(Key.RIGHT)) {
		_x += 1;
	}
	if (walls.hitTest(getBounds(_root).xMax, _y, true)) {
		_x -= 1;
	}
	if (walls.hitTest(getBounds(_root).xMin, _y, true)) {
		_x += 1;
	}
	if (walls.hitTest(_x, getBounds(_root).yMax, true)) {
		_y -= 1;
	}
	if (walls.hitTest(_x, getBounds(_root).yMin, true)) {
		_y += 1;
	}
}

I got one object caled walls and one caled ball(there is there I put the code).

Thanks
