[color=#115e94][font=Tahoma][size=3]I have created a movie where there are buttons I am calling the movie clip from the library by clicking the the button . Each movie clip is high in file size due to its large graphics. So, I have put a preloader into the first frame of each movie clip. The problem is, how can I change the order of the moive clip that is called inside the movie. Also I need to change the transparency of the layer I am hereby sending you the fla files also. I need your kind help sir.
