Where to put append?

Not sure where to put the append...

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>");
$modal.append('$dismissButton');
//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">
    <title>Modal Example</title>
</head>
<body>
    <h1>Modal Example Page</h1>

    <script src="//code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>
    <script src="js/app.js" type="text/javascript" charset="utf-8"></script>
</body>
</html>

I'm not sure what you mean by "needed to add alot more than I thought".

The solution is to add just this after line 9:

$modal.append($dismissButton);

Treehouse Moderator has changed self-assigned 'Best Answer' and has marked Steven Parker's response as "Best Answer." It is the correct solution and IS formatted for the Community correctly.

The clue in the question, as I read it, is that the button isn't displayed. So, without coding it for you, an append is missing from the button section... but the place holder must come after

Hope this helps :)

It seems you needed to add alot more than I thought...this finally worked:

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

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