You're missing the semi-colon and it doesn't require the "." at the end. It probably wants you to consume the role variable in the concatenation operator (+role).

Hi Adrian! -

You're wanting your string to say: "Adrian Storr: developer". It's important to remember spacing when using the + in concatenation.

If you code:

const msg = firstName + lastName;

you are going to get: "AdrianStorr" as a result. To fix this, we need to add several + to the above code.

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

... should do the trick for you.

it accepts:

let firstName = "Name";
let lastName = "Von LastName";
let role = 'developer';
let msg = `${firstName} ${lastName}: ${role.toUpperCase()}`;

but you could achieve a similar result for the msg using string concatenation (if they haven't covered the backtick syntax and string interpolation). So the last line in that instance might resemble:

let msg = firstName+ " "+lastName + ": "+role.toUpperCase();
