I need help modifying the (println) statement within the (greeting) function to use the variable (person).

Can someone explain to me what I'm doing wrong?

Thanks!

parameters.swift 
func greeting(person: String) {
    var person = ("XYZZY")
    println("Hello \(person).")
}

greeting("XYZZY")

the person variable is already defined in the parameter (person: String).

parameters are things that get passed to the function when it is called. you can use parameters in the body of functions you write.

you dont need to add a person var in the function body, just use the parameter:

func greeting(person: String) {
    //the value of whatever string that gets passed to the function will be inserted after Hello
    println("Hello \(person)")
}

also dont call the function until you get to task 3. if you put the function call in task 2 it might not pass you since its not expecting that to be there yet
