Here we need to include page inside main page and depend on query string.include files and output.

<?php

            if(!isset($_GET['blogerid'])){
            global $wpdb;
            $current_guid=null;
            $user_guids = $wpdb->get_results("SELECT DISTINCT wp_guid FROM wp_blogger_data");
?><table border=1 width="100%">
            <tr><th width='30%'>User Name</th>  <th width='30%'>Total Hits</th> <th width='30%'>Unique Hits</th></tr>

            <?php

            foreach ($user_guids as $user_guid) {
                         $username_by_GUID = $wpdb->get_row("SELECT `ID`,`user_login` FROM `wp_users` where `wp_guid` = '$user_guid->wp_guid'");
                         $unique_hits = $wpdb->get_row("SELECT COUNT(DISTINCT `ip_address`) AS `unique_hits` FROM `wp_blogger_data` where `wp_guid`='$user_guid->wp_guid'");
                         $total_hits = $wpdb->get_row("SELECT COUNT(`ip_address`) AS `total_hits` FROM `wp_blogger_data` where `wp_guid` = '$user_guid->wp_guid'");
                        ?>
                        <tr><td><?php echo $username_by_GUID->user_login;?></td>
                        <?php
                        echo "<td>".$total_hits->total_hits."</td>";
                        echo "<td>".$unique_hits->unique_hits."</td>";  
                        ///wp-admin/admin.php?page=wp-blogger-detail-view.php?id=<?php echo $user_guid->wp_guid;
                        ?>
                        <td><a href="<?php echo get_admin_url()."admin.php?page=wp-blogger-share-this/wp-blogger-share-this-admin.php&blogerid=$username_by_GUID->ID";?>">Delete</a></td>
            <?php
            }               
            ?> 
            </table>
<?php
            }
else
{

        include 'wp-blogger-detail-view.php';
}
