Hey Henry Peavler !

I'm guessing by trying to get through this myself that you're on step 2 of this 3 step challenge. The issue is on that last line you're trying to reset the value of a const (role) and a missing colon :.

We need to remove the let role = from your last line and just define a new variable role with your string concatenation. You may hit an error after that regarding a colon. You'll want to add this after the lastName and before the space between that and the role.

let firstName = "Trey";
let lastName = "Peavler";
const role = "developer";
const msg = firstName + ' ' + lastName + ': ' + role;
