Stuck on challenge task 2 of 2, JS, Storing & Tracking Info w/ Variables

I've tried a few different ways of writing this & I keep getting 'Bummer! Did you add the '#' character between 'id' and 'lastName'?

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

var userName = id.toUpperCase("id"+"#"+"lastName");
index.html 
<!DOCTYPE HTML>

<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

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

// Right now this is concatenating the string "id" and the string "lastName", instead of their values.
// Remember, you're calling the toUpperCase() method on the variable before the '.' only.
var userName = id.toUpperCase("id"+"#"+"lastName");

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

// You want to manipulate and concatenate the values of the variables. No quotes allowed!
var userName = id.toUpperCase() + "#" + lastName.toUpperCase();

also... this is correct. I totally missed that you need to call the method .toUppercase on each variable. Do as rydavim says. :)

Good answer rydavim!

Thank you so much..., that worked & made sense. I've been stuck here (embarrassingly) for days.

As it sits, JS thinks you're trying to use the strings "id" and "lastName", but you and I know that you really mean the variables with those names..

Remove the quotes from your variables.. this will solve your issue.

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

var userName = id.toUppercase +"#"+ lastName.toUpercase;

Like this. :)

I tried that, & then I got "Oops! It looks like Task 1 is no longer passing." Any other ideas? (Thank you)
