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!");

Treehouse TeacherHi there! See where we appended the placeholder to the modal? Well we created the variable for our dismiss button, but then we never actually appended it to the modal. Here's the line you need:
$modal.append($dismissButton);
I'll leave the placement of the line up to you

4,584 PointsCome on man, don't be so lazy! Try the challenges, it's how you will learn. Do not just copy and paste it. Yes someone will probably give you the answer here but you are not using this website correctly, challenges are designed to help you learn. You shouldn't do them just to move on, you need to learn! Otherwise, what's the point. So go do the challenge yourself and if you get stuck on a part, post a question relating to that part, not the whole thing.
