jQuery-On line 19, modify the code to set the attribute of src to imageLocation.

Somehow I made it through this challenge the first time around, but this time I am stumped.

Am I close?

Thanks to anyone who can assist!

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>");

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

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

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

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

  //Get child's alt attribute and set caption


});

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

imageLocation is a vaeiable now. Remove the "" and you'll be fine.

$image.attr("src", imageLocation)
