I can not create a code for two different variables

Hello I can not write the code for this question. Could you help? Marina

app.js
var id = "23188xtr";
alert (id.toUpperCase() + ('#') + (lastName.toUpperCase());

var lastName = "Smith";

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

You shouldn't put parentheses around the variables.

var userName = id + '#' + lastName;

Lee is generally correct, but fails to capitalize. Consider:

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