Audio not working

What am I doing wrong? Should be simple but I need some help. I want to get audio when one of the boxes is clicked. Is it possible to hear it from device that is running the merge cube?

Hi Mike, just place your when glass wall is clicked block before forever block or put your forever block inside run separately block.

As its name suggests, forever block makes code inside it to execute forever until you exit play mode, switch to another scene or break our of forever block using break out of loop block. So in your case program is stuck inside forever block and never adds click listener to the box.
