The challenge doesn't require you to use this method. Are you just practicing?

Hello Antonio,

Add another line with: console.log(msg); I think you will see your code works. You may wish to add a space between your lastName and your role.toUpperCase()

Not to get ahead but the challenge also accepts string interpolation. This should be the preferred method for concatenating strings since it's oh so clean. :)

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