Carousel not wo

Hello

I’m working on a carousel animation with a smooth transition. I’m having trouble getting it to work quite right — I can make it move from one image to another in one direction of the carousel, but not the other. I want a sliding, drag-style transition between the images.

It is supposed to have a round curve on the animation.

Thank you in advance for taking the time to read the above. I hope someone can help me.
