"try {
Element.hide("add_answer_link_for_post_-613772418");
Element.update("new_answer_form_for_post_-613772418", "<form
action=\"/answers\" method=\"post\" onsubmit=\"new
Ajax.Request('/answers', {asynchronous:true, evalScripts:true,
parameters:Form.serialize(this)}); return false;\">\n<fieldset>\n

Hi Manish Belsare
<% if logged_in? %>
<div id="add_comment_link_for_post_<%= post.id %>">
<%= link_to_remote "Add a comment",
:url => new_comment_path(post.blog, post),
:method => :get %>
</div>
please can anyone guide me wat does
"add_comment_ink_for_post_#{@post.id }" do???
From your view code add_comment_ink_for_post_#{@post.id } is some div
For example of @post.id=2 Then that div will be
add_comment_ink_for_post_2
page.hide "add_comment_link_for_post_#{@post.id }"
What this does is hide a div element As an example it hides the div
add_comment_ink_for_post_2

You say that you get this when you have implemented a new page, but
you have not shown the code of your page. It is therefore difficult
for anyone to suggest what is wrong.
