How to make storyline remember and show user's path?
I'm creating a presentation in geaography, starting with a map on which there are several paths to choose presented by several countries. Clicking on each country leads to a series of slides, then sends the user back to the map, in order to choose a new path. How can I make the program remember and show the paths that the user has already gone through? Is there a way to show him, on the map, the countries that he has already visited and to direct him to visit the other countries that he still hasn't visited on the map?
