In this exercise you had to set an external Parameter which looked sth like this:

func greeting(#person: String)

If you want to call this function now you have to set the person parameter first:

greeting(person: "Jerry")

This should do the trick :)

Tried this as well:

greeting = "Hello (Jerry)"

Result:

wift_lint.swift:11:21: error: use of unresolved identifier 'Jerry' greeting = "Hello (Jerry)" ^
