I'm trying to incorporate 2 games into one. I want to take the paddle ball game and add a function that when the ball hits a brick, the brick falls down and can be caught by a secondary paddle at the bottom of the screen that follows the now free moving first paddle.

I can't get the brick to fall it just stays up there and becomes a transparent sprite. The function that I added was "animateBrick". If anyone wants to see the full source file let me know I'll email it to them.
package {

// set event listeners

public function moveObjects(event:Event) {
movePaddle();
moveBall();
animateBrick();

}
public function movePaddle(){
//match horizontal value with the mouose
var newX:Number = Math.min(wallRight-paddleWidth/2,
Math.max(wallLeft+paddleWidth/2,
mouseX));
paddle.x = newX;
paddlez.x = newX;
var newY:Number = Math.min(800-paddleHeight/2,
Math.max(200+paddleWidth/2,mouseY));
paddle.y = newY;
}

function animateBrick() {
var lastTimez:int = getTimer();
var timeDiff:int = getTimer()-lastTimez;
lastTimez += timeDiff;
brickDY += gravity*timeDiff;
bricks.y += timeDiff*brickDY;
}

public function moveBall() {
//don't go here if in between balls
if (ball == null) return;
//get new location for ball
if (lastTime == 0) lastTime = getTimer();
var timePassed:int = getTimer() - lastTime;
lastTime += timePassed;
var newBallX = ball.x + ballDX*timePassed;
