okay, I think you are close to the answer.... first thing, if you create

var userName = whatever;
var userName = something else;

you are going to get a syntax error, because you can only declare a variable one time. If you want to do that you need to write

var userName = whatever;
username = something else;

The way I would solve this is

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

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

let me know if you have any questions about it or anything
