User cannot advance to next slide until Audio completes AND all objects have been selected
I have a slide where audio is playing in the background. While the audio is playing, the user must select each (there are three total) shapes to learn more. Once the audio is finished and the user has selected all three shapes, the next button should appear, allowing them to advance to the next slide. I have all my triggers set up correctly for my shapes. I also have the initial state of the "next" button as hidden. I obviously have not done something correct with my "Next" button. Currently my triggers are:
"Jump to slide / next slide/ user clicks / next"
"Change state of / Next / to normal / when media completes / audio 2 / on condition " and then I have each of the three shapes listed, joined with "AND" is equal to / selected"
Even when the audio finishes and I have selected all the shapes, the next button doesn't appear. Please help!
