Hey!

Okay, so first things first - .toUpperCase always comes with () at the end. Without the brackets at the end, the method will not work.

Now, let's break down the requirements of the challenge.

"Challenge Task 1 of 2 - Use the JavaScript .toUpperCase( ) string method to assign an all uppercase version of the id variable to the userName variable." --- The challenge wants you to turn variable "id" to an all uppercase (so you use id.toUppercase() as you did, except you don't log it to the console, that was not a requirement), and it wants you to store that in the "userName" variable. You store things in a variable like this: VARIABLE = THING YOU WANT TO STORE . Specifically for the task, it should go like this:

var userName = id.toUpperCase();

Following the above example, in the second step of the challenge you now have to add more stuff into the "userName" variable. It wants you to add a "#" symbol and an uppercase version of the "lastName" variable. I think this hint will help you, but let me know if you need more assistance.

Good luck!

Hey!

You only write "var" once, when you are declaring the variable. After that, when you want to add stuff to it, you only write the name of the variable.

In addition, # is a symbol. You can't .toUpperCase() it, like a letter, since it doesn't have a capital version.

So to pass the challenge you'll either do it like this: 

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

or just add it to the existing line of code, like this: 

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