Having issues with the 'next' button. I have four objects with conditions on them so that the next button is disabled till all four objects have been clicked. However I am struggling to find an option to change the state of the button. Ideally I would like the 'next' button opacity to be 50% or 'ghosted out' to show users that they should not click it until they have clicked on all four objects. Doe's this functionality within Storyline 2 to do this?
