3d class zooming

hello,
I did everythin that in the zoomig class here:

http://www.kirupa.com/developer/actionscript/zooming.htm

I created a movie clip that has a circle drawn in it (instead of the figure in the class…). and put three instances of it in the stage, I named them figureA, figureB figureC like in the tutorial and put all the code in the 1st frame of the stage.

but when running the movie (test movie) nothing happends

anybody has an idea why?
thanks
Yair
