I have var result = greeting("Tom") but it tells me it's the wrong value for result. Why is that?

Am I missing something obvious with this code for Challenge 2

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

return (greeting,language)

}

var result = greeting("Tom")

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

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

Hi sarahhale !

In Challenge Task 2 of 3 "Create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.)" you inserted a comma after the "Hello" by mistake and the challenge didn't like that. Everything else looks good.

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

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