PHP:

// Link to comments, trackbacks, etc.: 
                    $Item->feedback_link( array( 
                                    'type' => 'feedbacks', 
                                    'link_before' => '', 
                                    'link_after' => '', 
                                    'link_text_zero' => '#', 
                                    'link_text_one' => '#', 
                                    'link_text_more' => '#', 
                                    'link_title' => '#', 
                                    'use_popup' => false, 
                                ) ); 

this was the code that needed changing. changed 'feedbacks' to 'comments' and all is good. the file that they said this code was in was wrong however. for miami blue (the skin i use) i found this piece in the '_item_block.inc.php' file.

thanks for the help
