Tuples task 3 of 3

I am trying to complete task 3 of 3 but it always says not compiling. The assignment is Using the println statement, print out the value of the language element from the result tuple. Thank you!

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

    return (greeting, language)
}
var result = greeting("Tom")
println(language())

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

    return (greeting, language)
}
var result = greeting("Tom")
println(result.language) // or print(result.language) in Swift 2.0

What you're trying to do there is to call a function named language() which doesn't exist and that's why your code is not compiling.
