You have not defined any variable named "ul". But you do have one named "myList" that refers to a ul element.

Also, the "removeChild" function takes an element reference as an argument, not a selector. You might want to use the reference to the list item that was made on line 2 ("firstListItem").

Never put quotes around a variable name. Quotes create a string literal.
