Make "Next" button appear after all slide layers are visited
I have hotspots on a base slide that make a slide layer appear after clicked (there are 5 of these) and want the "Next" button to stay hidden until they have visited all five. I can't seem to make the "Next" button in the player do that using a number of different ways. I have tried making a True/False variable for all the slide layers and even adding a counter; none of these worked. Would anyone have a suggestion on how to do this? I would prefer that I don't have to make a button on the actual slide, but just sticking to the button in the player. Thanks.
