hi everybody! i`m trying to apply this function(prototype):  
\<%= link\_to\_function “reply”, “$(‘main-comment-form’)  
.hide()  
.appendTo(‘comment-#{comment.id} .form-placeholder’) //problem is here  
probably  
.fadeToggle(600);  
$(‘comment\_parent\_id’).setValue(#{comment.id});”%\>

after clicking the link form hides succesfully, but it doesn`t append to  
.form-placeholder
