The challenge is expecting an element collection but you're giving it a single element, so I suspect that message isn't exactly describing the results accurately.
The challenge asked you to: "select all links in the unordered list with the id of "gallery"". But what your code does is to select the element with the id of "gallery" (the list itself) instead. Just like you did in task 1, remember that links are identified by anchor ("a") tags. So you still want a collection of links, just this time the ones in "gallery" list.

You're correct. But the code challenge questions do lead you in the direction you need to go, but not directly.

231,248 PointsI guess that's why they call them "challenge" and not just "practice".

I figured it out on my own after I posted this question. Yes, the instructor was intentionally misleading with the "id" comment. Of course, it helps to really READ every element tag name in the index.html code so you know how deep to go with your string to be returned. The pattern to the answer of the first question of this code challenge is what the instructor is looking for. (I'm not trying to give the specific answers away.)
Thanks. This was driving me nuts for a while, & I knew it wasn't that difficult to begin with. Just a case of over thinking it.

231,248 PointsI meant the error message ("Was expecting 2 not 3.") was misleading, not the instructor! The challenge instructions are OK but you do need to read carefully.
