Hello! I've never used the forums before so I apologize if I'm misusing them.

I'm making a project where there is a button the viewer can press to change the backdrop to the next one, however, there are many backdrops, so I was hoping to make a button that the viewer can press to go back, so they don't have to cycle all the way through the backdrops again. I can't quite figure out how to code that, though, so I was hoping someone here could help?

Also, I accidentally posted this on the regular ‘scratch help’ forum, but I can't figure out how to delete it.

Thanks!
