Almost got it!

You're missing the backslash before (person), and Tom should be in quotes.

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

greeting("Tom")

Hey Chris,

Try this:

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

I hope this helps.
