Let's take this step-by-step. You start with:
func greeting() {
println("Hello")
}
You need to add a prameter to the function which is called person and is a String. That looks like:
func greeting(person: String) {
println("Hello")
}
Which is what you have done. Next up, the question says "Modify the println statement within the greeting function to use the variable person". So that needs you to incorporate the paramater, above called person, into the output of the println statement. That needs you to use string interpolation as you have nearly done:
func greeting(person: String) {
println("Hello \(person)")
}
Lastly, the challenge is to call the function using the paramater "Tom" - that's pretty straightforward:
greeting("Tom")
I hope that all makes sense!
Steve.

935 PointsThe next task asks to create a function that RETURNS the greeting rather than just printing it - when i replace 'println' with 'return' and error comes up. Any help?
Steve Hunter
57,712 PointsYep sure ...
First, you'll have to set the function up to return a string ...
func greeting(person: String) -> String {
println("Hello \(person)")
}
So that skeleton now takes a String as a parameter and returns one too. But we need to amend the body of the function too:
func greeting(person: String) -> String {
return "Hello \(person)"
}
Without seeing the challenge, that's the best I've got - let me know if it works!
Thanks,
Steve.
