I can't find the error here , can anyone help me

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.

js/app.js 
let navigationLinks = document.querySelectorAll('nav');
let galleryLinks;
let footerImages;
index.html

Hi! The reason your code is wrong is because you are selecting just the "nav". You may try this: let navigationLinks = document.querySelectorAll('nav a');

Hey , you are actually selecting the nav element instead of all the links within nav element . In order to select all the links within nav element you have to select all the anchor elements within nav element like this:

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