How do I Modify println statement within the greeting function to use the variable person?

// What am I missing from this challenge? It prints "Hello Tom" or is it suppose to print "Hello variable person"?

func greeting(String) { let person = "Tom" println("Hello (person)")

}

// CHALLENGE 2 / 3 : Modify println statement within the greeting function to use the variable person. For example, if you pass a person named "Tom" to the function then it should display: Hello Tom. (Hint: you must using string interpolation).

parameters.swift
func greeting(String) {
  let person = "Tom"
  println("Hello \(person)")
}

Hello Roderick: You are only missing one part of the challenge.

func greeting(person: String) { // you had to give it a parameter of type String. 
    println("Hello \(person)”) 

}

// call the function with a name in the parameter.
greeting("Tom”)
