can someone point out what i can't see been staring at this for a half hour lol

i can't see the error lol

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();
});

nothing is wrong with that code, the thing is, the event.preventDefault isn't in the challenge. its in the click function. let me know if it works, if it doesn't I'll keep looking.

$("#imageGallery a").click(function(event){
 event.preventDefault();

the even part is what is missing in the challenge
