    copied!<p>Since there's clearly a problem somewhere else... and since you're not fully using the potential of JQuery, I've taken the liberty of rewriting the code you've provided. Here it is :</p> <pre><code>&lt;head&gt; &lt;script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"&gt; &lt;/script&gt; &lt;script type="text/javascript"&gt; var _comment_counter = 0; function Comment(msg){ var comment = $('&lt;div&gt;&lt;/div&gt;') .attr('id', "comment" + (_comment_counter++)) .text(msg); $('&lt;input type="submit"&gt;&lt;/input&gt;').val('reply') .appendTo(comment); $('&lt;input type="submit"&gt;&lt;/input&gt;').val('delete') .click(function() { deleteComment(comment); }) .appendTo(comment); $('&lt;ul&gt;&lt;/ul&gt;') .appendTo(comment); return comment; } function addComment(comment) { $("ul#wall").prepend( $('&lt;li&gt;&lt;/li&gt;').hide().append(comment).fadeIn() ); } function deleteComment(comment){ comment.parent().fadeOut('normal', function() { $(this).remove(); }); } &lt;/script&gt; &lt;script type="text/javascript"&gt; $(document).ready(function(){ var _defaultValue = "Write a message"; $("#newMessageTxt") .height("200px") // ??? use a textarea ? .val(_defaultValue) .focus(function() { if ($(this).val() == _defaultValue) { $(this).val(''); } }) .blur(function() { if(/^\s*$/.test($(this).val())) { $(this).val(_defaultValue); } }) ; $("form#newMessage").submit(function(){ var msg = $("input#newMessageTxt").val(); if (msg != _defaultValue) { var newComment = new Comment(msg); addComment(newComment); $("input#newMessageTxt").val(_defaultValue); } return false; }); }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;div class="message"&gt; &lt;form id="newMessage"&gt; &lt;input type="text" id="newMessageTxt" /&gt; &lt;input type="submit" value="Submit" /&gt; &lt;/form&gt; &lt;/div&gt; &lt;ul id="wall"&gt; &lt;/ul&gt; &lt;/body&gt; </code></pre> <p>** <strong>TIPS</strong> **</p> <ul> <li>adopt a coding style, and use it <em>everywhere</em></li> <li>if you're using a library, use it or else you're not respecting the point above</li> <li>separate code and layout; HTML is a layout, Javascript is code. You shouldn't put socks in your t-shirt drawer...</li> <li>if you have a delete function, you should have an add function. This goes for all <a href="http://en.wikipedia.org/wiki/CRUD_%28acronym%29" rel="nofollow">CRUD</a> operations</li> </ul> <p>Now, this code works, you should perhaps start from there.</p>
