Next Button disable-enable + sound stop for good
Hi all. In my course I have a set of slides (I attached them) which built a sort of chain. What I want and cannot handle is:
Main slide - tiles lead to sub-slides (not layers)
- stop audio as soon as someone click on any of the tiles and don't play anymore when coming back to the Main slide from a sub-slide.
- disable NEXT button from start. Enable NEXT Button after all sub-slides have been visited.
- have state of tiles changed when respective sub-slide has been visited or the tile was clicked (this I have already but when I want the sound to stop for good...I just don't know. Like, resume main slide when re-visiting or not?)
Subslides are ok as they are.
I would appreciate any kind of idea.
