Lightboxed content not displaying
I'm creating a trivia game where a marker moves along a motion path and displays a lightbox when the motion path completes. The lightbox displays a quiz question that must be answered before the marker advances to the next question.
I have layers for subsequent moves of the marker, and everything works EXCEPT, when the lightbox for the quiz question displays using a trigger on the layer, there is no content! I can see the navigation controls, the transparent background, but no content. I saw another discussion with a similar problem, but it appeared to be browser-related. This happens in Preview and Published.
Can anybody help?
