You forgot a set of parentheses after id.toUpperCase. All methods need a set of parentheses in order to work whether they take an argument or not.

Your code:

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

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

The correct code:

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

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