Need help with PICK ONE activity!
I've created a simple "pick one" activity where participants are shown three pictures and have to select the correct one. I want each picture to change its state when the participant clicks on it. However, I'd also like the pictures to go back to their original state when another picture is clicked. How can I do this? I tried with different layers by checking the option "hide other layers" but still when one picture is clicked, the other pictures' states dont't revert to their original ones. So in the end, if the participant clicked on every picture before submitting his answer, the three pictures will have the same state (selected).
