Hey Amanda!

Check the error message you are seeing when failing this question. It's pretty helpful: Check the parameter you're using for 'nextInt()'. Hint: 0 through 9 is a total of 10 choices.

I haven't taken the course yet, but I was able to determine what to do by this alone. You might want to reconsider using n: as well. Good luck! 👍🏻
