The question challenge says "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)."
func greeting() { var person = Tom println("Hello (person)") }
what am I doing wrong here

\(person) will work.
Also, you're missing your parameter in the function, though, maybe that's just on the forums.
Hope that helps.

2,518 PointsI did that, none of these work either:
func greeting(person: String) { println("Hello (person)") } greeting(Tom)
or
func greeting() { var person = "Tom" println("Hello (person)") }
or
func greeting() { var person: String = "Tom" println("Hello (person)") }

11,940 PointsOh jeez, I'm sorry, I missed another issue.
You're not supposed to assign a variable to "person", and you're not supposed to call the function. Just modify the
printlnstatement to include the variable "person".Your first example, minus "greeting(Tom)" will work if you include the backslash before "(person)".
You can put your code on the forums so it's displayed correctly by following this detailed post: https://teamtreehouse.com/forum/posting-code-to-the-forum
In this case, use "swift" as the language.
