Whoa, thanks! I did not even realize it says "change" in quotations in the instructions! I guess I need to read more carefully. I did not realize that when it says "change" it means exactly that word. Thanks for the help.

For this challenge an addEventListener needs to be added to both lines. Here is the syntax for one of them:

navigationSelect.addEventListener("change", navigateToValue);

How did you know that the event is specifically called "change"? It could have been anything! Would another word fit suitably representing the visitor's selection of an option from the select menu? What if they change it from "change"? Will we know about that? Can you say where the documentation says "change" for this event?
