I am working on an app and I have various things like sentences or pictures that I would like to come up in random order. For example, I would like the first item to come up, user to click a NEXT button and then another one of my items to come up (could be random or sequential but I'd prefer random...with no repeating until all items have been displayed once). I need to know how to establish a counter and to call items to be displayed. I'm new at app inventor and would appreciate any helps as to which blocks to use and what to do in the viewer to make this work. Just making an app for fun for a friend as a gift! Thanks in advance! I hope my question was clear enough.
