Javascript To Upper Case Question

Where am I going wrong?

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

var userName
userName = "id.toUpperCase()";
index.html
<!DOCTYPE HTML>

<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

  1. Check that each statement ends in a semicolon.
  2. Note the distinction between these things: userName = "id.toUpperCase()"; and userName = id.toUpperCase(); They are not the same. In the first, username's value is set to "id.toUpperCase()". In the second, username's value is set to "23188XTR". Details, details :)

You need to assign the uppercase version of id to the pre-made userName variable.

userName = id.toUpperCase();
