:point_right: Looks like you have a stray Console.ReadLine(); on a line by itself near the end, and after you do your printing.  You'll need to remove that.  That's for both of the two examples you show.  That first one also needs a return inside the catch block so it doesn't try to print when there is a bad value entered.
And in case you need them, here are some hints (https://teamtreehouse.com/community/c-basics-final-challenge-task-2-of-3) for the second task of the challenge.
