blog app pagination in archive

Hello, i using perch blog app (v 5.0) and have following problem:

this is my archive.php

// defaults for all modes
                $posts_per_page = 1;
                $template       = 'post_in_list.html';
                $sort_order     = 'DESC';
                $sort_by        = 'postDateTime';

                // Have we displayed any posts yet?
                $posts_displayed = false;

                /*
                    perch_get() is used to get options from the URL.

                    e.g. for the URL
                        /blog/archive.php?cat=news

                    perch_get('cat') would return 'news' because cat=news.


                    The code below looks for different options in the URL, and then displays different types of listings based on it.
                */


                /* --------------------------- POSTS BY CATEGORY --------------------------- */
                if (perch_get('cat')) {
