Reset a dial when user clicks on Previous button

Hello everyone,

I have 3-position dial on a slide. Position:

- 1 sends the user to the "wrong answer" layer;

- 2 is the neutral position;

- 3 sends the user to the "good answer" layer.

I tried different triggers but just can't find the right combination in order to reset the dial to the neutral position (2) when clicking on the previous slide button of the layers.

Any suggestions?

Thanks!
