Idiot from the Uk, it sounds so easy but i just cant make it work !!!!!!!

In the following tasks you'll be required to select various elements on the index.html page. In the app.js file on line 1, select all links in the nav element and assign them to navigationLinks.

This being the first challenge at the end of Javascript and he DOM, why i cant make this work i am just so lost !!!!!!!!!!!!!!!

js/app.js 
let navigationLinks = document.getElementsByClass('selected');
let galleryLinks;
let footerImages;
index.html 
<!DOCTYPE html>

Use descending selectors for your .querySelectorAll()

so... .querySelectorAll('nav ul li a');

Stumped me too
