Returning Elements Using CSS Selectors

https://teamtreehouse.com/library/javascript-and-the-dom-3/getting-a-handle-on-the-dom/return-elements-using-css-selectors

Once again I'm stumped; this time on the third objective in the above link. I keep getting error messages no matter what approach I use.

Here's the objective:

"Next, select all <a> elements inside the unordered list with the ID gallery and assign them to the variable galleryLinks."

This is my answer: 

let footerImages = document.querySeletorAll('footer a');

Here's the error message:

"There was an error with your code: TypeError: 'undefined' is not a function (evaluating 'document.querySeletorAll('footer a')')"

What am I doing wrong?

Yea, that error message isn't too helpful. And you were right that the target part of your descendent selector should be "a". But the function name should be spelled "querySelectorAll" (with a "c").

And for the container part "the unordered list with the ID gallery" would be "ul#gallery" (or just "#gallery" since IDs must always be unique) instead of "footer".

Your solution didn't work but (' footer img') did. Thanks for your help anyway.

Looks like we got the tasks confused. The objective you listed above is for task 2 (which is the one my answer was for, but you must have already solved), yet apparently you were actually working on task 3 which has this objective instead:

"Finally, select all images inside the footer element and assign them to the variable footerImages."   :see_no_evil:

No, I was referring to the third task. I thought I made that clear. I figured out task two on my own but it doesn't really matter now. Once again, thanks for your help.
