I'm stumped on a challenge... What am I doing wrong?

http://www.screencast.com/t/tXhvxz776QA

app.js 
var id = "23188xtr";
var lastName = "Smith";
var stringToShout = id.toUpperCase();
lastName.toUpperCase();
var userName = id + '#' + lastName;
index.html 
<!DOCTYPE HTML>

Hey Matt!

it looks like you're performing the right operations, just not storing them in the proper variable. For example, your stringToShout variable is the one that's uppercased. The id variable was left unchanged. Same for the the name except it wasn't assigned to any variable. In the code below, I just did all the functions on the username variable. Hope this helps!!

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

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

It's as simple as changing

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

to

var id = "23188XTR";
var lastName = "SMITH";

I used your code and just changed these two variables and it worked for me!

It should look like this

var id = "23188XTR";
var lastName = "SMITH";
var stringToShout = id.toUpperCase();
lastName.toUpperCase();
var userName = id + '#' + lastName;

However, I believe you only need to change "xtr" to "XTR" since you uppercase the lasename.

I've found that the Treehouse code checking really wants the strings to look exactly the same, so even a change in case is considered incorrect.

Hi Matthew,

You are over-complicating this just a bit but you have all the correct pieces. You can use the .toUpperCase() method while assigning the userName variable.

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

If you do it this way you don't need any intermediate steps.

Thanks!
