Start/Stop Button Wheel

I know there are a lot of posts about this, however, I can't seem to find one that's helping me fix my current rabbit hole I've dove down.  I'm very new to Articulate and am trying to make a wheel that spins when the user clicks the "spin" button in the center.  That same button then turns into a "stop button" when the wheel is moving and the quadrants highlight the possible selections as the wheel spins. 

Then, when the user clicks "stop" a quadrant is highlighted and eventually I'll figure out how I want them to get to that part of the learning but I can't even get this wheel working properly so one thing at a time! :)

I'm running into a few issues:

1) When I hit spin, the "stop button" appears but doesn't work and nothing stops.

2) When I change things around, it starts and stops but won't start again and then the "stop button" doesn't appear. (I used another layer when I tried that one, not sure if that was the proper way to handle.  It worked but created a new problem.)

Any help would be much appreciated.
