Hello everyone. I trying Figma prototypes with variables but it is harder a bit. 😦

I have a question.

I prepared a slider with 4 images switching. I set a variable for these four images for a button to switch from 1st to 2nd each time. but it does not switch from the 4th image to the 1st image, it jumps to the 2nd image. So it does not return to the beginning. Where am I making a mistake?

How can i restart my prototype? how can i jumpt to the 4th (cannibal) to first image? (vermithor)
