Use a variable in one scene to trigger action in other scene?
I'm wondering if it is possible to use a variable on a slide in one scene to trigger an action on a slide in a separate scene.
For example, I want to use a course menu slide. The learner selects one of the 3 lesson options on that slide, goes through the material, comes back to the menu slide, chooses another options, etc. Once all of the menu options (lessons) have been selected and seen, the Continue button on the menu slide displays, taking the learner to a course summary and evaluation.
I thought perhaps I could set a variable on the last slide of a lesson to change to a value of "1" when the timeline starts (or some other trigger). I would do this for each lesson, setting a separate variable for the last slide in each lesson. Then on the menu slide I would say that if those variables had all be set to "1" the Continue button would change its state to "normal" and appear.
This isn't working. Should it?
Thanks for any guidance you can provide,
