How to make a toggle button alternate between 'Normal' and 'Reverse' Playback modes

Hi, so I made an on/off switch and connected it to the Playback Mode in a Zone. The Value of the switch reads: @type:Zone/@id:a0004. My hope was to make a button that could toggle between ‘Normal’ and ‘Reverse’ modes. What happens is that it toggles between ‘Normal’ and ‘Reverse One-Shot’ instead. I was able to get radio buttons to work, by setting their OnValue to 0 and 1 respectively. My assumption was that an on/off switch would be equivalent and send a 0 or 1 as well, but that doesn’t seem to be the case. Any insight on how this works and what it would take to implement?

Thanks in advance! :slight_smile:
