I am having the hardest time with this seemingly simple code challenge.

I've tried so many different ideas with no results.

app.js 
var id = "23188xtr";
var lastName = "Smith";
id.toUpperCase ();
lastName.toUpperCase ();
var userName = id + '#'+lastName;
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
<script src="app.js"></script>
</body>
</html>

It looks like you haven't changed the value assigned to the id and lastName variables on lines 3 and 4. For instance:

var a = "foo";

console.log(a.toUpperCase()); // FOO
console.log(a); // foo

// Reassign new value to a
a = a.toUpperCase();
console.log(a); // FOO

So you're on the right path, but you need to assign the result of calling the String.toUpperCase() method back to the variables in question in order to have the change stick for future uses of that variable.

Hope that helps! I'd be glad to help out more if not.
