What you need is not a form tutorial but a basic knowledge of programming, regardless the language or framework you use.
Try to think your flash movie as a unity and not a collection of frames where various input boxes and dropdowns and radio buttons cannot communicate with each other.
To let them all serve your purpose, store their contents to a structure of global variables. When you need those values no matter the frame you are or how far from the initial form, their data will be in front of you, ready to assign them to other controls, or calculate or send to a server or whatever...
