Comments list with paging feature and Ajax effect

Hi, I want to add paging functionality to the list of comments for an article. This is ok, I can do it. But I have a problem with the page loading. When the user clicks on a specific page number the whole page is loaded. But I want just to refresh the area where the list is displayed. I also changed the click action in order to access a php page but I don’t know how to display from that php the tpl template that I want. Can anyone help? Thanks

Hi, long time ago :)could you solve the problem? How did you implement the paging feature? thanks!
