Task 1 is no longer passing. On line 2 of app.js, select all links in the unordered list with the id of "gallery

It's the same answer it was in task one. I only change the answer to number two.

js/app.js 
let navigationLinks = document.querySelectorAll('nav a');
let galleryLinks = document.getElementsById('#gallery a');
let footerImages;

Hi there! You're doing great, but you've run into the most common reason for a "Task 1 is no longer passing" message. You've introduced a syntax error into your code which means that the code can no longer be interpreted. This includes the code that you already did which was correct.

You wrote: getElementsById(), but this is not a valid method as the DOM may only have one element with a particular ID. ID's are unique to the page. You may not, for example, have two <div> elements with id="myDiv" The correct method is getElementById(). Note the singular version here. However, even changing it to this will not work.

Instead of the getElementById() try a querySelectorAll() instead.

I think you can get it with these hints, but let me know if you're still stuck! :sparkles:
