I am kind of stuck

I have been trying for half and hour and I still can't get this to work

func search(#name: String) -> String? {
    let names = ["Doc","Grumpy","Happy","Sleepy","Bashful","Sneezy","Dopey"]
    for n in names {
        if n == name {
            return n
        }
    }
    return nil
}


if let n = names {
println("found")
}

Hi there,

You need to call the function called search. Something like:

if let result = search (name: "Doc") {
  println("Found")
}

I hope that makes sense!

Steve.
