Reset so that the student can try another

I’m working on an AB where the S’s are finding the area of a triangle. At the end I want to have a button which resets everything so that they can try another one. I can’t get it! Ideas? I am sure I have to use capture… but understanding those commands is beyond me at the moment!

@Jay shared this on Twitter the other day. I know this question has popped up frequently here, so hopefully it works for your case.

Thanks. I really struggle with the resetting interactions.
