Compiling navigation links

I'm attempting to select three navigation links within the first unordered list, but for whatever reason it's saying that I'm doing this exercise incorrectly. I know WHY it's wrong, but the solution eludes me. Any guesses as to what the problem could be? I would like to move forward.

js/app.js 
let navigationLinks = document.querySelectorAll('a');
let galleryLinks;
let footerImages;
index.html 
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">

The instructions say to "select all links in the nav element", but if you use just "a" as the argument to querySelectorAll it will get all links on the page, not just those within the nav element.

This would be a good place to use a descendant selector, where you name the container and then the target, separated by a space.

Sounds good. I think I know how to proceed if I have any other questions I'll let you know down here.
