I'm sure I have this right and everthing works perfectly when I create records but whenever I submit I get "Looks like something went wrong, please try again later."

I've searched round the web and confirmed my solution is the same as others (it is) but although the records update correctly, I can't get Trailhead to agree.

Is anyone else having any trouble?
