Here you go:

var id = "23188xtr";
var lastName = "Smith";

var userName = userName + "#" + lastName.toUpperCase();

They want you to combine all in one variable declaration.

Thanks but for some reason it didn't work.

Joyce, I just pasted it again in your Challenge, and the Challenge accepted it. So I'm wondering if the problem isn't a different one. Very occasionally I've found that the challenge editor doesn't forget an old answer, and keeps giving a Bummer after I've fixed the problem. When that happens I close the browser completely. Then reopen it and try again. With one exception (a Treehouse bug) that solved the problem.
