What is wrong with this code? It keeps asking me if I've used println() once and I have.

I'm not sure what this wants me to fix.

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")
    }

}

Hello kamal bains:

You are very very close to the answer ! I can give you the answer or I can just give you a hint of what to do, and perhaps you will figure it out on your own, and if you still don’t understand, then I can give you a better explanation.

Here is the hint: Closing bracket ;)

Good luck, please let me know if it helped you figure it out.

Kamal,

Let us know if you understand the hint that Jhoan gave you. Your code is correct, but its placement is off.
