Hi Michael,

You have the return type setup correctly but you've also changed the name of the function and removed the person parameter which wasn't asked of you and you've also declared task 2 within the greeting function whereas it needs to be declared on the outside as well as you need to called the greeting function which you're currently not doing.

See the below.

func greeting(person: String) -> (greeting: String, language: String) {
  let language = "English"
  let greeting = "Hello \(person)"

  return (greeting, language)
}

var result = greeting("Tom")

Hope that helps.

I know my variable isn't correct, I'm aware that it isn't being passed to the greeting function. But I have no idea how to do it.
