Bummer! You need to call 'greeting()'

24,464 PointsOk, first, what you have discovered is recursion, thus calling a function again from within. But, this is not what you have to do here.
func greeting(#person: String) { // your code to print the string }
greeting(person: "Jerry")

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

7,515 PointsI get the first part of this of calling an external parameter as you are defining an external parameter called person but the second part I'm not understanding. I don't get the need to have the code to print the string? I'm stuck on what it is asking for? I understand the greeting(person:"Jerry") as you are calling the greeting function. func greeting(person greeting: String) {

7,515 PointsOk so right now I have this func greeting(person greeting: String) { println("person") greeting(person: "Jerry") } Still trying to figure out what it wants or what I'm missing.

3,619 PointsI think you're trying to make more of the challenge than what it's actually asking of you. You also need to add the label name to the parameter (in the parenthesis). Mind your placement of the brackets, too :-)
Your code should look like this:
func greeting(#person: String) {
println("Hello \(person)")}
greeting(person: "Jerry")
