javascript strings problem

Complete the assignment to the userName variable by adding a # symbol followed by an all uppercase version of the lastName variable. In other words, using string concatenation so that the final value of userName is "23188XTR#SMITH".

Is it just something small I am forgetting to put in?

app.js 
var id = "23188xtr";
var lastName = "Smith";
id.toUpperCase(userName);
var userName = id + "#" + lastName;
document.write(userName);
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>

You need to remove line 3 and place before document.write :

userName = userName.toUpperCase();

I changed the code to this but it doesn't work.

var id = "23188xtr"; var lastName = "Smith"; userName = userName.toUpperCase(); var userName = id + "#" + lastName;

The code should be, as described above:

var id = "23188xtr";
var lastName = "Smith";
var userName = id + "#" + lastName;
userName = userName.toUpperCase();
document.write(userName);

the toUpperCase needs to be after you declared the variable, so just switch lines 3 and 4

your really close on this all you need to do is concatenate the variables and the string into one variable. like this:

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

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

and there you go. Happy coding.
