Like so:

let firstName= "Lee";
let lastName= "Louw";
let role= 'developer';

let msg = `${firstName} ${lastName}: ${role.toUpperCase}`
console.log(msg)

Whenever you invoke a function, you must add parentheses after the function name. For example, to make Jonathan's suggestion of a template literal work, it would look like this:

let msg = `${firstName} ${lastName}: ${role.toUpperCase()}`;

You can also solve this with concatenation, but you need to use the variables by name and fix the string literals.
