How to control the users' movement when clicking on a standard Storyline check box
I'm using Storyline's built-in check boxes to track the progression of a users' movement. The story is to have them click on external links read the articles or view the videos and come back to Storyline and check off that they understood what they read or viewed. Once they get to the last link the last check box only then should they be able to progress to the next page which will be an assessment page.
So my goal is to have the last check box have a trigger that will have a statement that will say unless "you must completed all of the check boxes above before continuing on to the next page". Can someone help me build this trigger with variable?
