not working, why?

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

var userName = id.toUpperCase() lastName.toUpperCase()

userName += '#' +lastName

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

var userName = id.toUpperCase()
lastName.toUpperCase()

userName += '#' +lastName

UPDATE: My comment is terribly inaccurate. Do not use.

You need to put some semicolons after your statements: 

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

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

userName += '#' +lastName;

Also, What are you trying to accomplish? I believe "+=" only works with numbers.

Actually, semicolons are optional at the end of a line (but considered a "best practice").

Try:

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

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

userName += '#' +lastName;
