Hi Savannah~

The challenge wants you to build the variable msg out of the other variables that you've already declared. It's also asking that it looks similar to "Carlos Saldago: developer"

You can do that by concatenating the strings:

let msg = firstName + " " + lastName + ": " + role;

Or by using a template literal:

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

Notice that in the first example I gave I added in a space between the first two variables in quotes, and then a colon and space between the last two in quotes -- this is because they are not part of the variables we're using. Otherwise the result would look like CarlosSaldagodeveloper. This isn't needed in the template literal since everything inside the backticks is read as it is typed, except for the variables declared within ${}.

Also -- remove the parentheses in your first two variable declarations. They shouldn't be there, the quotes are what determine it is a string. And lastly firstName and lastName are intended to be set as names, not as "First Name" and "Last Name". If you don't want to use your own name just use the one in the example like so:

let firstName = 'Carlos';
let lastName = 'Saldago';
let role = 'developer';
