Next, select all links inside the unordered list with the ID gallery and assign them to the variable galleryLinks.

Your query select all will select all/both the ul elements - the challenge is asking you to just select one, the one with the id of gallery. Correction - as per Daniel below, read the requirement carefully - you need to target the links not the list

Thank you!!! I had been banging my head because I misread the question thinking I was suppose to capture the <li> tags, not the <a> tags 🙄

Break this down

Next, select all links inside the unordered list with the ID gallery and assign them to the variable galleryLinks.

  1. Select: ALL "Links" which means <a> tags (NOT Unordered Lists)
  2. Where: Inside the <ul id="gallery">

So, Similar to your previous

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

find the 'a' tags inside the 'ul' with the '#gallery' id.
