This should work:

var myList = document.querySelector('ul');

var firstListItem = document.getElementById('first');

myList.removeChild(firstListItem);

The problem is you're trying to pass in the reference to firstListItem as a string.

It's okay for the first 2 lines because they are references to HTML classes and ID's. In order to pass in variables to methods simply pass in the name of the variable.

myList.removeChild(firstListItem);

Thanks A lot Jonathan!!
