what is wrong in my code?

var room = new XMLHttpRequest();
room.onreadystatechange = function () {
  if(room.readyState === 4 && room.status === 200) {
    var rooms = JSON.parse(room.responseText);
    var statusHTMLr = '<ul class="rooms">';
    for (var i=0; i<rooms.length; i += 1) {
if (rooms[i].available === true) {
      statusHTMLr += '<li class="full">';
      } else {
      statusHTMLr += '<li class="empty">';
      }
    statusHTMLr += rooms[i].room;
      statusHTMLr += '</li>';
    }
  statusHTMLr += '</ul>';
document.getElementById('roomList').innerHTML = statusHTMLr;
  };

};
room.open('GET', '../data/employees.json');
room.send();

          ```

Apart from using correct JSON file, if the rooms available is true you have to give the class Name of "empty" to the list item instead of full.

Happy Coding !!!

on room.open ('GET', '.../data/employees.json'); you forgot to change employees.json to rooms.json hope this helps

https://w.trhou.se/rrd7muid5o Here's how I did it. I missed the class of "rooms" at first, and tried using the class from the first UL. Then I found it.
