Trouble with two strings in a function...

I'm trying to complete the "Hello Tom" challenge, however my second parameter is not being accepted... Any help would be great!

parameters.swift 
func greeting(greet: String, person: String) {
    println(greet person)
}

Shane,

Not a bad start. However, The instructions do state that you are only supposed to pass one parameter into the greeting function. Therefore, only (person : String) should be used. Another issue with your code is that you need to use String interpolation within the println statement. To do this, we surround our variable with parenthesis inside the String and place a \ in front of it.

Example:

    func honkHorn(animal : String) {
        println("I am honking my horn at a \(animal)")
    }

    honkHorn("Duck")

Please let me know if this helps.

Regards,

Chris
