Overlay: not allowing me to click on image. Images are remaining in their greyed out state. Any suggestions?

Image should get selected and enlarged in center of the page. 

//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>");

$overlay.append($image);

$overlay.append($caption);

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


//Capture the click event on a link to an image

$("#imageGallery a").click(function(event){
  event.preventDefault();
  var imageLocation= $(this).attr("href");

  $image.attr("src",imageLocation );
  $overlay.show();

  var caption = $(this).children("img").attr("alt");
  $caption.text("$captionText");
});

$overlay.click(function(){
  $overway.hide();

});

just a small typo, also in 

 var caption = $(this).children("img").attr("alt");
  $caption.text("$captionText");

it should be

var captionText = $(this).children("img").attr("alt");
  $caption.text("$captionText");

dunno why both of those wouldn't except the first JavaScript markdown, if you need any help let me know I hope that works for you. When I adjusted those two things mainly the overlay typo, it worked like a charm.

so there are a couple of slight issues, the biggest one is this 

$overlay.click(function(){
  $overway.hide();

it should be

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