firstName, lastName, and role are all strings, so you need to concatenate them with additional strings of colons and spaces to get the correct formatting.

For example:

let greeting = "Hello";
let name = "John";
let message = greeting + ", " name;

Hope this helps

let msg = firstName + ' ' +lastName +' : ' +' ' + role; This was final correct answer to the challenge question. I have intentionally added spacing to view more comfortably here. The string concatenation must be used with + and spacing between objects to be right thanks for the insight.
