Using multiple variable conditions in a trigger
I have a slide with three buttons. Each displays a layer, sets a unique variable to True, and displays a button to return to the base layer. Once the user has visited all three layers, in any order, and all three variables = True and the user is back on the base layer, I want a layer displaying a Continue (to next slide) button to appear.
What I would like is a Trigger that reads, "Show layer Continue when all three variables = True." But I can only indicate one variable, not all three in the When field of the trigger. I can list the variable values in Conditions, but I have no When. Users can select the buttons in any order. I don't want them to have the option to Continue until they have visited all three.
I tried using "when timeline starts" with the variables values in Conditions, but the Continue layer did not display. I added a textbox with the variables referenced for troubleshooting. All three are setting to True when desired. Why is the Continue layer not displaying and how can I make this work?
Thank you in advance!
