JavaScript JavaScript Basics (Retired) Storing and Tracking Information with Variables Using String Methods

Problem with string concatenation

The problem is that I can't pass the checkpoint. I just started this JavaScript course so obviously I'm doing something wrong but I don't see it. Maybe I'm to close to it. It keeps asking if I added the "#" sign between the two variables?

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

var userName = console.log(id.toUpperCase() + "#" + lastName.toUpperCase());
index.html
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
<script src="app.js"></script>
</body>
</html>

Hi Bjorn,

I don't think you need to console.log the result. Your toUpperCase methods and concatenation all look correct...just remove the log and you should be fine.
