I am having trouble figuring this one out. Can someone help me?

I am trying to figure this one out. Can someone show me the correct way this is supposed to run. I can't seem to figure it out.

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

var userName= id.toUpperCase();
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Well you got the first part right. Now you need to concatinate. The symbol used in JavaScript is (+). So you need to add a # sign after that id you just added. And then the lastName all upper case (as the id). So:

id (to upper case) + # + name (to upper case)

Try figuring the code yourself. If you can't, here it is (really try it yourself):

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