How do I combine both of the variables into one string?

I cannot seem to add both the ID and Username into a final string and connect them together with the # sign... please help. Thank you!

app.js 
var id = "23188xtr";
var lastName = "Smith";
var userName = id.toUpperCase
var lastName =
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Hi there,

For this one, you want to use string concatenation - we can do that when assigning a string value by using the + sign. From the challenge, we know we want userName to have:

  • id in caps
  • a # sign
  • lastName in caps

So, we can get the final userName value by putting in all three of those things, connected by + signs, like this:

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

Hope this helps - let me know if it doesn't make sense.
