Having trouble no matter what i try i can't assign the return value to result. IN Task 2

in task 2 of the quiz it asks me to create a variable result and assign the return value to result. Ive tried a lot and it tells me same thing you need to assign return value greeting to result.

Can some one please teach me the code to do this

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

    return (greeting, language)
}
    let result = greeting

Hi Joshua,

The question for task 2 is as follows:

Create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.)

What this means is we need to create a variable called result and assign is the return value of greeting which means we need to call this function and pass it the argument Tom as the parameter.

var result = greeting("Tom")

Happy coding!

This is still currently failing in Treehouse editor.

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

    return (language, greeting)
}

var result = greeting("Tom")

Gets the error

Bummer! You need assign the return value of the 'greeting' function to 'result'
