Variable changes across slides
I'm trying to set up an interaction whereby a variable changes from false to true once a student reaches a certain slide. I would like an object to change states from hidden to normal on a previous slide when the variable is true. That way when a student revisits that slide, a new object will appear on the screen.
I believe I've got everything set up correctly, I've tested to see if the T/F switch adjusts an object from hidden to normal on the same slide that the T/F trigger is on and it works. However, it doesn't seem to effect previous slides.
