Disabling NEXT button
I'm working with a colleague on a Storyline 2 project. We are attempting to build a simulation for legacy software (menu driven green and yellow print on a black background). We want to make it possible for a learner to click on a line in a green on black menu and have Storyline 2 take the learner to the new menu or a screen that lists options for their next action. We want to disable the NEXT button so the learner can't just click on it and go from screen to screen.
What would we need to do to disable the NEXT in this type of interaction?
