Trying to assign a tuple to a variable and not sure how to do it!

The Challenge is this: Create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.) and my code is attached. Having trouble knowing what the variable 'result' would look like and how i pass the string to Tom

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



    return (language, greeting, result)
}

Hello Becky:

What the challenge is asking is for you to create a variable and assign it whatever the function will return to you.

I will modify your code just a bit, and then the rest you can do it. It will make sense once you see it.

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

    return (language, greeting)
}

// Call the function and declare the variable here. 

If you can't solve it or if there is anything that you do not understand, please let me know, and I can go into more details. So far you were doing great.

Good luck
