Ajax stage 2 challenge syntax error

I'm trying to figure out this 2nd challenge code without having to look at the answer but I don't understand where the syntax error is coming from. Uncaught SyntaxError: Unexpected token <

Here is my code(sorry for any formatting issues with this message. First time posting):

var xhr2 = new XMLHttpRequest();
xhr2.onreadystatechange = function(){
  if(xhr2.readyState === 4){
    var rooms = JSON.parse(xhr2.responseText);
    var statusHTML2 = '<ul class="bulleted">';
    for (var i=0; i<rooms.length; i++){
    if(rooms[i] === true){
      statusHTML2 += '<li class="full">';
    } else {
      statusHTML2 += '<li class="empty">';
    }
      statusHTML2 += rooms[i];
      statusHTML2 += '</li>';
  }
    statusHTML2 += '</ul>';
    document.getElementById('roomList').innerHTML =statusHTML2;
  }
};
xhr2.open('GET','../data/rooms.json');
xhr2.send();

Look at line 16. I've added a comment

var xhr2 = new XMLHttpRequest(); 
xhr2.onreadystatechange = function(){ 
    if(xhr2.readyState === 4){ 
        var rooms = JSON.parse(xhr2.responseText); 
        var statusHTML2 = ''; for (var i=0; i'; 
    } else { 
        statusHTML2 += ''; 
    } 
    statusHTML2 += rooms[i]; 
    statusHTML2 += ''; 
} 
statusHTML2 += ''; 
document.getElementById('roomList').innerHTML =statusHTML2; 


} }; // Not sure what this is. This is probably your error.


xhr2.open('GET','../data/rooms.json'); 
xhr2.send();

Also look at line 5. You have a random single quotation after the last i.
