Hey stuck on this question, what am I doing wrong?

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

var userName = id.toUpperCase(); var lastName = "Smith".toUpperCase();

var userName = id +"#"+lastName;

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

var userName = id.toUpperCase();
var lastName = "Smith".toUpperCase();

var userName = id +"#"+lastName;

You have the right idea but they want you to append the # and lastName to what is already in userName i.e. pretend you don't know what is in userName, how would you do it? Also lastName is already declared below id so you can not declare it again, same with userName (when you are re-using a variable you do not have to type 'var' each time, that is only to declare/initialize it the first time). The code should look like this:

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

var userName = id.toUpperCase();

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