I'm trying to create a computer based training simulation that will include a list of lessons. The user will select a lesson, review the contents, and return to the list to select another lesson. Since it won't be mandatory to review each lesson in order, I would like the simulation to reflect 'faded' icons (we'll say folders) for the lessons that have been reviewed.

Finally, once all lessons have been reviewed, I'd like a notice (following the list of folder icons) to read: You are now ready to Test!

Questions:
What kind of scripting would be involved?
What else (besides Flash) would be needed?

If anybody has any input/suggestions/comments/sarcasm to offer please reply. Thanks.
