// I watch the .swf . . . . . magic
// Now I want to connect the .as file to a .fla file on my PC (FlashCS4) 
// I have been learning to work on the stage for about a year now but am a real beginner with AS3
// Q1. How do I download and use wonderfl code alongside my own animation
// Q2. Would anyone be willing to act as a mentor as I try to learn AS3
// Thanks to you all
