it seems treehouse uploaded the wrong challege need help

i got the first challenge but the second one about the caption is killing me

js/app.js 
//Problem: User when clicking on image goes to a dead end
//Solution: Create an overlay with the large image - Lightbox

var $overlay = $('<div id="overlay"></div>');
var $image = $("<img>");
var $caption = $("<p></p>");

//An image to overlay
$overlay.append($image);

//A caption to overlay
$overlay.append($caption);

//Add overlay
$("body").append($overlay);

//Capture the click event on a link to an image
$("#imageGallery a").click(function(event){
event.preventDefault();
  var imageLocation = $(this).attr("href");
  //Update overlay with the image linked in the link
  $image.attr("src", imageLocation);

  //Show the overlay.
  $overlay.show();

  //Get child's title attribute and set caption
  var captionText = $(this).children("img").attr("alt");
  $caption.text(captionText);
});


//When overlay is clicked
$overlay.click(function(){
  //Hide the overlay
  $overlay.hide();
});

Can you show me the code when you change it, so the changed code you are saying should work, I'll run it and see if it works for me too. Because I changed the alt to title and it worked for the challenge
