I haven't checked anything else, but I saw a typo in the "input" variable when you define it. You have "inout". Fix that typo and see if that helps you out.

You need to define what the button is as well. Your code currently states there's an event listener for a variable called "button", but the computer doesn't know what that's referencing. Define what "button" is equal to (hint: you need to reference "sayPhrase" in this case).
