Bummer! Your greeting printed "Hello Tom" when called with "XYZZY" as the parameter. It should have printed "Hello XYZZY". Preview

Check the code i inputed and please give feedback, confused by error message

parameters.swift 
func greeting(person: String) {
    println("Hello \(person)")
}
greeting("Tom")

if you are on task 2, remove the function call at the bottom. Looks like thats whats giving you the error.

task 2 states: Modify the println statement within the greeting function to use the variable person. For example, if you pass a person named "Tom" to the function then it should display: Hello Tom. (Hint: you must use string interpolation).

it does not ask you to call the function yet, so remove the call:

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