It looks like you have the first part of the challenge figured out. It works for me when I copy and paste your code as is, that being said, i'm just assuming you are asking about the second part of the challenge. With that part, remember what you did to select the links in the nav. It is going to be in the exact same format, but instead of selecting links in the nav, its under the ul with the id "gallery" . Remember that when using "querySelectorAll", we need to specify the attribute using the corresponding symbol. In this case, id is "#". So you would select the id (#gallery) with the children being the links (a) so your javascript code for the second part should look something like this:

let navigationLinks = document.querySelectorAll("nav a");
let galleryLinks = document.querySelectorAll("#gallery a");
let footerImages;
