Can't complete Challenge Task Escaping Output

Hi! Can't complete this challenging task. What can I modify in that code?

views_listing_edit.php
<?php require_once("controllers_listing.php"); ?>
<html>
<body>

    <h1>Edit Listing</h1>


    <form method="post" action="views_listing_edit.php">
        <table>
            <tr>
                <th>
                    <label for="name">Name</label>
                </th>
                <td>
                    <input type="text" id="name" name="name" value="<?php if(isset($name)) { echo $name; } ?>" />
                </td>
            </tr>
            <tr>
                <th>
                    <label for="link">Link</label>
                </th>
                <td>
                    <input type="text" id="link" name="link" value="<?php if(isset($link)) { echo $link; } ?>" />
                </td>
            </tr>
            <tr>
                <th>
                    <label for="description">Description</label>
                </th>
                <td>
                    <textarea id="description" name="description"><?php if(isset($description)) { htmlspecialchars($_POST[$description]);} ?></textarea>
                </td>
            </tr>

You'll need to escape the output using the htmlentities() function.
