why is this telling me to add a ':', I'm doing exactly as it says

app.js 
let firstName = "Christian";
let lastName = "Citalan";
let role = 'developer';
let msg = ( firstName + ' ' + lastName + ':' + role);

Hi Christian,

This is a simple, common mistake. If you look really carefully at what it tells you when it fails, notice that there is a space after the colon. So put the space in your concatenation after the colon and you got it.

Keep on coding!
