Matthew, The question is asking you to assign a value to navigationLinks. It says the value should be every link in the nav, so you have to remember how to select elements on a page with JavaScript. The most usable way to do this is to use the querySelectorAll function, which is usually applied to the document element. Then, links ("a" tags) in the nav can be targeted by selecting nav a. So the full answer is:

let navigationLinks = document.querySelectorAll('nav a');

Make sense? Hope this helps!

Hehe, glad it worked out. If you don't mind, mark this as the right answer so others will know you're all square and so I get some fake internet points. Cheers! :)
