Function - println is in body of func, but getting error message

I am putting println within the curly braces of the func but the bummer message is telling me it needs to be in the body of the function. What am I doing wrong here?

greeting.swift 
func greeting() {
var hello = "Hello"
println("\(hello)")
}

greeting()

try removing the function call ( greeting() ) from the bottom. task 1 did not ask you to call the function

func greeting() {
var hello = "Hello"
println("\(hello)")
}

also, you could just print out the string literal "Hello" without assigning it to a var first if you wanted:

func greeting() {
println("Hello")
}

thank you! I tried to non-var way first and it gave me the same error message about println needing to be in the body of the function. I bet my calling the function is the issue - thank you Stone!

Yep that was it - by not calling the function, it went through fine. Thanks!
