Totally stuck on this one...

This is challenge task 2 of 3 on the tuples portion of Swift Functions and Operationals. Honestly, what I did during the tutorial doesn't resemble what I think I need to do in this challange. I'm just looking for a little guidance. Thanks!

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

    return (greeting, language)
}

Set the type of the tuple, then call the function:

var result: (greeting: String, language: String) result = greeting(person: "Tom")

I've found that you need to space out your " : " or else you get errors in Treehouse. So... 

(#person : string) -> (greeting : string, language : string)
