How do I add the #? I have this: var userName = id.toUpperCase(); + '#' + lastName.toUpperCase();

What's the solution?

app.js
var id = "23188xtr";
var lastName = "Smith";

var userName = id.toUpperCase(); + '#' + lastName.toUpperCase();

Hey Katherine,

You have a semicolon in that last line. It's not supposed to be there... probably a typo.

It should be:

var userName = id.toUpperCase() + '#' + lastName.toUpperCase();
jobbol
seal-mask
.a{fill-rule:evenodd;}techdegree
jobbol

A semicolon in Javascript is like the period at the end of a sentence. The compiler is confused by your bad grammar!

Or, a much better/DRYer solution (IMO) is to group all in parentheses:

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

Sure... but DRY only applies in a real-world context — this is just a basic practice problem.
