Making a program like this, i need to be able to function like this.
Splash page -> Directions of how to make dinosaur -> Page like the one in link with creator -> THEN i need to be able to go to more instructions, -> go back to page with the dino you made and then need to add a name -> more instructions etc.
I have no idea how to make such a thing.
Try solving it one item at a time. First search Google for a tutorial on "AS2 drag and drop tutorial" to gain an understanding of how to create the dinosaur bit. Then take that creation and have it as a movieclip that you keep open/present if the intention is to contiue where you left off.
