My colleagues and I were hoping you could help us resolve a recurring issue. We've been creating interaction slides in which the learner needs to reveal slide layers by clicking objects on the screen. The user is not meant to advance to the next slide until after all layers have been viewed.
In order to do this, we have been creating a trigger that disables the NEXT button when the timeline starts, and another trigger that changes the NEXT buttons state to 'normal' once the state of each of the clickable objects is 'visited.' It sometimes works in preview, and most of the time doesn't.
