below is the code I am useing I have created a simple frame with 2 layers one named body and one named Code in the code frame I have

// how fast should the ball move?  
ballYspeed = 5;  
ballXspeed = 5;

onEnterFrame = function () {  
// set the speed and position of the ball  
ball.\_y += ballYspeed;  
ball.\_x += ballXspeed;  
// if the ball hits the top or bottom  
// reverse its Y speed and position  
if (ball.hittest(bottom) || ball.hittest(top)) {  
ballYspeed \*= -1;  
}  
// if the ball hits the left or right  
// reverse its X speed and position  
if (ball.hittest(left) || ball.hittest(right)) {  
ballXspeed \*= -1;  
}  
};

In the body I have 4 walls all named top bottom right and left they are movies and they are named in there instance the same I have a circle I named ball and made it into a movie and named it ball yet when I run the flash file the ball flys off the page and doesnt bounce inside the boxes?
