Stuck on this Challenge Question

For this challenge question, here is the code I am inputing:

func greeting(person: String) -> String { let person = "Tom" return person }

let person = greeting("Tom") println("Hello (person)")

The error message I receive is that this does not allow for different names to be passed through (i.e. Fred instead of Tom).

Can anybody provide some guidance?

Hi, while using let person = "Tom" you are defining a constant (let), in your case you might want to use var instead of let or better not use extra line and return just the greeting with string interpolation:

func greeting(person: String) -> String {
    return "Hello \(person)"
}

Hey Stepan, changing it to var and the suggested code did not work. Any other thoughts?

It actually did. I made a small error in what I wrote. Thank you so much for your help.
