Remove the quotes from both userName and lastName of app.js, they are variables and not actual strings. You can add quotes to better space the output. console.log(userName.toUpperCase() +" "+ lastName.toUpperCase());

Don't forget the # in between.

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

Good luck!

Hi Luciana,

Because you are targeting the variables userName and lastName, you don't want to put quote marks around them. You use quote marks for string elements.

So, you just need to change this:

console.log('userName'.toUpperCase() + 'lastName'.toUpperCase());

to this:

console.log(userName.toUpperCase() + lastName.toUpperCase());

Hope that helps,
