It's great to let users explore content on their own. But sometimes you need to ensure they view the full timelines on the slides and complete the interactions. For example, this might be required f...
The icons for closing layers on slide 1.3 don't work because their Initial state is Disabled. That means the program can't recognize when someone hovers over them or clicks them, so they're never changed to Normal. Instead, start them in the Normal state, but don't show them until just before the timeline ends. (Alternately, you could start them Disabled, and trigger them to change to Normal when the timeline ends.)
The triggers that disable Next when the timeline starts would run if a user revisits the slide. They need conditions to prevent that from happening if the user has completed the requirements. For example:
Note that the conditions are connected with "or" (not "and"). That means the trigger will run if either variable is False.
You don't need the number variables to track that the layers are viewed. You can enable Next using just the T/F variables.
Note that the conditions are connected with "and" (not "or"). That means the trigger will only run if both variables are True.
I fixed these issues for the Section 1 content in the attached file. That should help you figure out how to fix the issues for Section 3.
