What is the expected after 'if' condition?

I'm on the Task Challenge 2 (of optionals) and when I put my code I got this error... swift_lint.swift:16:33: error: expected '{' after 'if' condition if let result = names("Doc")

I've used if-let function thing but is my code in the wrong place, am I missing something, or am I not even close?

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 = names("Doc") 
    println("Found")  
}

Hello Zachary : You are not calling the function. Instead of using names use **

 if let result = search(name: "Doc").

If you need a better explanation let me know.

Good luck.

I placed the code under the return nil and recieved this error...

swift_lint.swift:16:40: error: expected '{' after 'if' condition if let result = search(name: "Doc") ^

Am a placing the code in the wrong place or is it something else?
