I think the question asks you to return "Hello (person)", and you call a function by saying the function name, followed by a pair of parenthesis, and in the parenthesis, you pass in the arguments. So it should look like this:

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

}

greeting(person: "Jerry")
