Is someone who can explain better?

Finally, add a # symbol and lastName in uppercase to the end of the userName string. The final value of userName is "23188XTR#SMITH".

app.js 
var id = "23188xtr".toUpperCase();
var lastName = "23188XTR#Smith#";

var userName = id;
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Hi Kanishka.

It looks like you've gotten muddled up somewhere along the line. It's easily done. Especially when you're me. :)

You successfully applied the toUpperCase() method in task one. But you need to assign the change to the username variable.

What you need to do for the next part is a little bit of concatenation ... which is combining 2 strings to make them into one.

You'll need to call toUpperCase a second time.

Like this

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

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