Call Function

As per usual... going wrong. Not sure why either. I don't know if anyone else feels the same way but the training videos aren't completely aligned with the tasks that follow. Can someone help me out please :(

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

Hi Josh,

You'll want to include the parameter from your function header (in this case, it's 'person'.)

greeting(person: "Jerry")

Hope this helps!
