let galleryLinks = document.getElementById('gallery').querySelectorAll('a.href');

did not work for question 2 until I reloaded the page, then i just pasted what I had created over it and it worked

js/app.js 
let navigationLinks = document.querySelectorAll('nav a');
let galleryLinks = document.getElementById('gallery').querySelectorAll('a.href');

Ran into the exact some issue when I tried to submit my solution. Just got the "Was expecting 2 links not 3" until I refreshed, thanks for the tip!

Hope it gets fixed so it won't confuse future students.

EDIT: Hm, realized I'm stuck on the 2nd challenge.. After I refresh, submit again and it says "Good job!", it just won't load the 3rd challenge, just keeps on with the 2nd over and over..

:point_right: Your query seems to be looking for more than it should.

The task 2 challenge asked you to "select all links in the unordered list with the id of gallery", but your queryselectorAll argument of 'a.href' selects only links that have a class of "href". Removing the unnecessary class selector should resolve your issue.

But you could also accomplish the task using a descendant selector like you did for task 1, which would eliminate the need for the getElementById call:

let galleryLinks = document.querySelectorAll('#gallery a');
