Optionals in Swift

This is the code that I have for this example and when I place it into Xcode it works out correctly but it does not appear to be accepted on the challenge.

Any suggestions? Thank you =)

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(name: "Doc") {
      println("Found")  
}

The fix is live. Happy learning! (also, I'm not certified to let you know if you are crazy or not. Maybe we need to do some psychology courses :)
