I need to make the image or shape rotate to the right when the variable is incremented.

Hello, i've been here for about a week looking for one information for my project. Thought you could help me. I need to make the image or shape rotate to the right when the variable is incremented. And when it decreases, the object must also return, rotating to its original position. Maybe there are articles or ideas on this topic. I already try to use 3 objects, 1 state is normal and hidden when the animation of the second one starts. The third one will appear when the animation ends. In the same way, work in the opposite direction, but only once. But if the variable is incremented and then decremented and when the variable is incremented again the object is not animated. I'll leave the file below, thanks

P.S. I use Articulate Storyline 3
