Still goes to dead end on image-click despite same code as video

I've checked my code several times and I have the same code as the video, but mine still has the images go to a dead end. preventDefault and overlay not working. Any help would be appreciated - getting frustrated! Code:

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

$overlay.append($image);
$("body").append($overlay);

$("#imageGallery a").click(function(event){
  event.preventDefault();
  var imageLocation = $(this).attr("href");
  $image.attr("src", imageLocation); 
   $overlay.show();
});

$overlay.click(function(){
  $(this).hide();
});

//Thats because you did not assign any  div to $overlay. copy paste this code it will work.
var $overlay = $('<div id="overlay"></div>'); 
var $image = $("<img>");

$overlay.append($image); 
$("body").append($overlay);

$("#imageGallery a").click(function(event){
event.preventDefault();
var imageLocation = $(this).attr("href"); 
  $image.attr("src", imageLocation);
  $overlay.show(); });

$overlay.click(function(){ 
  $(this).hide(); 
});


// this is complete code.

i added the proper markup to both the codes above. Both are the same, hinting that it is most likely a browser problem for the asker
