assign upper case version of the id variable to username.

this is my solution: var userName += id.toUpperCase();

It throw an error. Does anyone know what do I do wrong?

app.js 
var id = "23188xtr";
var lastName = "Smith";
var userName += id.toUpperCase();
index.html

Oh you're so close here!. You're trying to append the id to userName which doesn't have anything in it so it doesn't really understand what you're going for. What we want here is a simple assignment operator which is a single equals sign. Take a look:

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

var userName = id.toUpperCase();
