Creating a function

Hi everyone!

Please, tell me what I am doing wrong. Have a task: Modify the println statement within the greeting function to use the variable person. For example, if you pass a person named "Tom" to the function then it should display: Hello Tom. (Hint: you must use string interpolation).

here is what i do:

func greeting(person: String) {
    println("Hello, \(person)")
}

greeting("D").

When I copy it to Xcode, it prints the result correctly, while the treehouse test says that there is a mistake.

Thanks, I figured it out. the problem was in coma after "hello". I removed a coma and it worked:)

Hello :

Everything seems to be ok, but you should pass it the name “Tom” instead of using “D”.
