I am a little lost

I started the variable result but can't seem to go forward. please help.

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

Here you go:

func greeting(person: String) -> (greeting: String, language: String) {  //make return type a tuple, with names
    let language = "English"
    let greeting = "Hello \(person)"

    return (greeting, language)  //return a tuple
}

var result = greeting("Tom")     //call the function
println(result.language)         //print the language from the returned tuple

The result variable needs to be created outside the function, and it needs to call the function with a parameter: "Tom".
