It looks like you have a few issues:

  • nothing called "name" has been defined
  • there should not be an empty space at the beginning or end of your firstName or lastName string value
  • make sure you're adding one space (" ") between firstName and lastName
  • make sure you're concatenating ": " to lastName and role 
let firstName = 'Carlos';
let lastName = 'Salgado';
let role = 'developer';
const msg = firstName + " " + lastName + ": " + role;

The example in my answer passes task 2. You must still have something different.

let firstName = 'Carlos'; let lastName = 'Salgado'; let role = 'developer'; const msg = firstName + "Carlos " + lastName "Salgado: " + role;

Your code is still different, comparing to the example code in my answer should make the problem clear.

let firstName = 'Carlos'; let lastName = 'Salgado'; let role = 'developer'; const msg = firstName + "Carlos" + lastName + "Salgado: " + role;

Make sure you're adding one space (' ') between firstName and lastName.

am i missing the space ? "Carlos " like tihis ?
