JS Basics. add toUpperCase & concatenating String error in test

My test is... add a # symbol and lastNamein uppercase to the end of the userName string. The final value of userName is "23188XTR#SZMITH"

final issue prior says task one no longer completes criteria!!! I go back and step One passes. Software has been a bit glitchy this afternoon.

var id = "23188xtr"; var lastName.toUpperCase = "Smith"; var userName = id.toUpperCase(); userName += "#" +=lastName;

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

var userName = id.toUpperCase();

userName += "#" +=lastName;

Looks like your syntax for Task 2 is a little off. .toUpperCase() is a JavaScript method, so it requires an open and close parenthesis at the end to invoke it. You can invoke it directly on the lastName variable, or invoke .toUpperCase() on lastName as you're concatenating userName. I would recommend using .toUpperCase() not on the variable declaration itself, but at the time when you need to concatenate userName. Otherwise, you'd be overwriting you're original lastName and you may need "Smith" later on instead of "SMITH". Here's what I did:

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

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