Hi Ioana, in the app.js file, insert the following code:

$( "li:hidden" ).show();
$( "div:hidden" ).show();
raul colon
raul colon

raul colon
raul colon

I still don't understand why that one is correct, but when we put a const and go through the whole process, it picks it as wrong?

why is this necessary

$( "div:hidden" ).show();

Shouldn't div remain hidden.

I did the same thing: const $hiddenElements = $('body').find(':hidden'); $hiddenElements.show();

It works but got the same error you did. I think it is just how the application treehouse is using evaluates cant handle passing the values as a variable.

Your way was correct as well.
