by returning the function "greeting" you are just making the function call it's self. you need to return 'the greeting' the function is making.

//first add "->String" so the function knows to return a string
func greeting(person: String)-> String {

// then return the string greeting "Hello \(Person)"
    return ("Hello \(person)") 
}

//No need for additional variables
