named_parameters challenge 2 confusion

Seem to be stumped again on a challenge. First I tried using the [ -> String ] but that didn't work either.

named_parameters.swift

1 let person = "Jerry" 2 func greeting(#person: String) { 3 return greeting(person: "Jerry") 4 }

named_parameters.swift 
let person = "Jerry"
func greeting(#person: String) {
   return greeting(person: "Jerry")
 }

Hope this helps. 

func greeting(#person: String) { 
  println("Hello \(person)") 
}
greeting(person: "Jerry")

thanks. It seems so logical now. I didn't realize I should keep the println command, although now I see it says to always add the code to what's already there. And rather than storing "Jerry" value as a constant you can eliminate code by calling it within the function. Just like the lesson was trying to point out. Duh!
