Using variables and/or conditions on buttons to trigger a new slide
I am trying to create a slide where I have 6 buttons that link to slides that come up as light boxes when clicked. The buttons can be chosen in any order. After the sixth button is clicked and that light box slide is closed, I want a new slide to appear. I was able to get the new slide to come up at the time that all six buttons were clicked based on a condition that was added to a trigger but that is too soon on the sixth button because then they don't see the lightbox which is set up as a slide with a lightbox trigger. I want the trigger to be when the sixth lightbox is closed that the new slide appears. Does it matter if I have the lightboxes as layers or new slides using the lightbox trigger? And/or should I set up a variable to somehow count when the lightboxes are closed?
