Enable next button after SOME layers are visited.

• Trigger: change the state of next button to disabled when timeline of slide starts
• Create a number variable to count clicks
• Trigger on each layer: add +1 to number variable when timeline of layer starts
• Trigger: change the state of the next button to normal when var = 2

Something to that effect

Tom is right, of course, but I prefer step 3 to be set at the end, rather than the beginning. That prevents the learner from opening the layer, closing it without doing whatever it requires, and still getting credit. Attach that trigger to whatever action hides the layer or returns to the base.

Thank you Tom and Walt for taking the time to answer my question.

Walt, I like the way you think, but the layers are simply read and "X" out.

Tom, I attached a graphic where I display all the triggers I created based on your instructions, yet I still have two questions:

Your layer needs a trigger to adjust var add 1 when timeline starts/ends (depending on what you do)

I created a quick tutorial and attached a file

Tom, It worked like a charm!  Thank you so much for taking the time to create a .story file and a tutorial - those really helped a lot.  I never would have thought to trigger each click.  Variables are still a hurdle for me - I have yet to break through. :)

Glad to hear that Tom's tutorial and project file were helpful, Dan! 🎉 

In case you haven't come across this yet, I'd love to pass along one of our On-Demand Webinars that helps users get comfortable with variables! Hope that it helps you break the ice trying this feature out!
