I think this it. Make sure that the constant is named "result". Also you have a typo in the name you're searching for, "Doc". You have "Ddoc" You also want to print "Found", not culprit. I think "culprit" was only for the video lesson. You're getting there though. Don't get discouraged. Here's the code.

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

Thanks bud but i got the answer, thanks again for your help, keep helping people
