What am i doing wrong? :-(

This seems like it should work. What am I doing wrong?

search.swift 
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 result = search("Doc")  {
println("Found")
}

You need to add a label when calling the method.

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