Adding variables..

I don't think I have this down quite right. Is there something I'm missing? Or am I doing this wrong?

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

var userName = id.toUpperCase();
userName = id + '#' + lastName;
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Hi there! You're doing great, and you're really close here. But they don't just want the id to be uppercase, they also want the lastName to be upper case. It seems like you might have missed that bit of the instructions. It is possible to do this all on one line of code. And because you are so close here, I'm going to just leave these hints. But if you're still stuck, please let me know! :sparkles:

Argh, I'm so close I can taste it! I don't think I'm getting how to add both variables in one line to upper case.

This was my failed attempt:

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

var userName = id.toUpperCase() lastName.toUpperCase();

userName = id + "#" + lastName;

Oh, still close! Take a look at how I did it.

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

This one line will take the id and uppercase it, then concatenate the pound sign/hash tag in the middle, then add the upper case version of lastName onto the end.

Good luck to you! :sparkles:
