The code is…

vel\_x = 10;  
vel\_y = 10;  
onEnterFrame = function () { ball.\_y += vel\_y;ball.\_x += vel\_x;if (ball.hitTest(left) || ball.hitTest(right)) {vel\_x = -vel\_x;}if (ball.hitTest(top) || ball.hitTest(down)) {vel\_y = -vel\_y;}};

It was just what I was looking for! The ball.fla still works if I change the settings to 2.0, but gives errors in 3.0. What changes would be necessary for 3.0?  
Thanks and Take Care,
