You are ending your statement with a semi-colon after your .toUpperCase() method. In the instance that you use concatanation to build your variables, any method/function calls need the semi colon removed. Like so.

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

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

notice on the id method, I didn't use a semi-colon, because that ENDs the statement. :)

You're on the right track though!
