You're pretty close, but I see two issues:

  • the assignment of "list" is unnecessary (and it is not used)
  • the "parent" is not needed, "prepend" should be applied directly to $(this)

For future questions, please describe the issue in more detail.

You created "list", but you weren't using it for anything.

And the task asks you to add a checkbox to the beginning of each list item, and the list item is what "this" represents.

Also, if you take the "parent" you get the list itself (ul), and it's not correct HTML to add anything to a list other than another list item.

I don't know what you mean, what's a "tree house group"?

That must be related to the kind of subscription you have.
When I go to that link, I see "Bummer! You must be an organization administrator.".
