:point_right: It looks like you have the right idea.

But the challenge asks you to filter only text input elements ("INPUT"), not list items ("LI").

You are on the right path, the tricky part is that the challenge is asking for text input while you are specifying the list items. Change your 'LI' to 'INPUT' and it should work.
