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

var userName = id.toUpperCase();

This should work. :) Don't worry about to make lastName into uppercase.

Hi Levente! You're so close here that I'm just going to give some hints. You are doing the id.toUpperCase() part correctly. However, you are writing it to the document, which wasn't asked for by the challenge. The challenge asks for that part to be the value assigned to the variable userName.

I think you can get it from just these hints, but let me know if you're still stuck! :sparkles:

I am also stuck. Here's what I have:

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

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

It won't allow this for some reason. I realize I might be doing more than what is asked, but the error messages suggest otherwise.

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

var userName = (id.toUpperCase());

This should help.
