I can't find bug

I don't get it, where is the bug?

js/app.js 
//Create the Modal
var $modal = $("<div id='modal'></div>");

//Create a placeholder for text in the modal
var $placeHolder = $("<p id='placeHolder'></p>");
$modal.append($placeHolder);

//Create a button to dismiss modal and add it to modal
var $dismissButton = $("<button>Dismiss</button>");

//Hide modal when button is pressed
$dismissButton.click(function(){
  $modal.hide(300);
});

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

//A function to show a modal
function displayModal(message) {
  $placeHolder.text(message);
  $modal.show();
}

//Show an example modal
displayModal("Hello World!");
index.html 
<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="css/style.css" type="text/css" media="screen" title="no title" charset="utf-8">

    <h1>Modal Example Page</h1>

Hi there! If you look directly above the declaration of the $dismissButton you can see another declaration for a $placeHolder variable. This was then appended to the modal. Your dismissButton is already declared, but never appended to the modal. So Treehouse is asking you to write the line that actually appends it to the modal. You can do it the same way the placeHolder was appended :smiley:

I hope these hints help, but let me know if you need more information! :sparkles:

:mailbox_with_mail: I got your message.

:point_right: It looks like you never append the dismiss button to the modal.

Right after you define the button on line 9, I would expect to see a line like this:

$modal.append($dismissButton);

Oops, I didn't realize this was a challenge — I don't usually give spoilers. :stuck_out_tongue_winking_eye:
