why is this not the right answer?

i'm supposed to simply call the function with the name Jerry. this seems so easy but i cant get why i'm not doing it correct?

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

I have no idea about Swift, only was reading about it during lunch breaks when i was bored but i believe that if you provide an external parameter name for a parameter (in this case Person), then that external name should be used while calling the function:

greeting(person: "Jerry")
