How do you add two different .toUpperCase variables to combine? Ex. "23188XTR# + SMITH"

im stuck here.. i cant figure out how to add these to variables together where all of them are uppercase. Whats wrong with my code?

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

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

Hi Nicolaas,

You have userName spelled wrong on your last line of code. It is case-sensitive.

Hmmm... I copied your code and changed just the one letter and it passes for me. Maybe you have other changes in your code since then?

Note that on the task there is an 'important note' that reads :-Important: In each task of this code challenge, the code you write should be added to the code from the previous task. This simply requires you to solve it this way

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

It should add to the earlier code. I believe this will help you out. Regards,
