Codes not working..I can't figure out why..

I've done everything even retyping it out and it matches up with what dave was doing, but for some reason it only shows the room number in gray text on the page.. i cant figure out what i did wrong..here's the code:

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
    if(xhr.readyState === 4) {
        var employees = JSON.parse(xhr.responseText);
        var statusHTML = '<ul class="bulleted">';
        for (var i=0; i<employees.length; i += 1){
            if (employees[i].inoffice === true) {
                statusHTML += '<li class="in">';
            } else {
                 statusHTML += '<li class="out">';
            }
            statusHTML += employees[i].name;
            statusHTML += '</li>';
        }
      statusHTML+= '</ul>';
      document.getElementById('employeeList').innerHTML = statusHTML;
    }
};
xhr.open('GET', 'data/employees.json');
xhr.send();

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

Check your relative paths. I'm not sure what your file structure looks like, but this line doesn't match where your employee data should reside.

- xhr.open('GET', 'data/employees.json');
+ xhr.open('GET', '../data/employees.json');

Thank you! That worked..not sure why that was overlooked in the video, but that fixed my problem.
