Code-Challenge issue - Selecting li on the dom with nth-child

Hi!

Trying to select all <li> in the <nav> by using this code. The system reads back to me, 'was expecting 3 links not 4' - where could the fourth link be coming from? And yet if I change nth-child(-n+1), the system rightly tells me 'was expecting 3 links not 2'. Is this a roundabout way to select these <li>? where is my code breaking down?

js/app.js 
let navigationLinks = document.querySelectorAll('li:nth-child(-n+2)');
let galleryLinks;
let footerImages;

Hi there! You are meant to be selecting all links in the nav element. The <li> is a list item. Remember, links are denoted by the anchor tag or <a> element.

Try it again with this hint in mind, but let me know if you're still stuck! :sparkles:
