JQuery I got an error can someone help?

I got a Bummer! it says the last element in the modal is the placeholder, not the button. Did you use 'append()' to append the button to the modal

Take a moment to read the code in the app.js file. The code should display a modal or pop-over window (built with HTML). In the modal window there should be a place for a message to display and a button to dismiss or close the modal. Check out how the code runs in the preview. There's something wrong. The dismiss button isn't showing in the modal. Can you fix it?

//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!");

Hi Lester,

You're simply missing a statement to append the button! 

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

Hope this helps. :)
