Works on Chrome console but not here?

Is there something wrong here? I tried this in Chrome dev tools and got the desired result, but not here.

app.js 
let firstName = 'Kim';
let lastName = 'DiPasqua';
let role = 'developer';
let msg = `${firstName} ${lastName}: ${role}`;
let roleUpper = role.toUpperCase();
let msg = `${firstName} ${lastName}: ${roleUpper}`;

Hey Kimberly DiPasqua,

You have declared msg variable twice. let variable can be updated but cannot be re-declared.

There are two ways you can pass this challenge by using string concatenation or template literals. I will present you with both:

String Concatenation

let firstName = 'Kim';
let lastName = 'DiPasqua';
let role = 'developer';
let roleUpper = role.toUpperCase();

let msg = firstName + ' ' + lastName + ': ' + roleUpper;

Template literals

let firstName = 'Kim';
let lastName = 'DiPasqua';
let role = 'developer';
let roleUpper = role.toUpperCase();

let msg = `${firstName} ${lastName}: ${roleUpper}`;

To learn more about let variables, check out this website: https://www.w3schools.com/js/js_let.asp

Hope this helps!

Hi

I think what the challenge is asking for is that toUpperCase is used on the role variable within the msg template literal.
