Помогите настроить снипет

// Blogger Snippet
// Created By: Ralph Dahlgren
// Based on the original EtoBlog snippet created by hugelmopf
// Last Modified: 2005-12-21
// Purpose: Creates and/or maintains a table of blog entries categorized by document id and can also be used to maintain multiple blog tables
// Use: [!Blogger!] - uses the table named etoblog for storage
// Use: [!Blogger?blog=blogtable!] - uses the table named blogtable for storage
// Use: [!Blogger?blog=blogtable&showAuthor=true&showDate=true&dateFormat=m/d/Y&height=400px&width=400px&permissions=edit_document&users=winkum,blinkum,nod!] - uses all available options

// Database table to use for storage (shouldn't need to be changed)
// entries will be grouped by document id so multiple blogs can use one table
$blog = isset($blog) ? $blog : "etoblog";
$tbl = $etomite->db.$blog;

// Should the authors name be displayed? Defaults to true
$showAuthor = isset($showAuthor) ? $showAuthor : "true";

// Should the last modified date be displayed? Editing an entry changes the date to the current time
$showDate = isset($showDate) ? $showDate : "true";

// Custom date formate based on the PHP date() function
$dateFormat = "l F jS, Y g:i a"; // Monday October 10th, 2005 4:37 pm

// Set the height of the WYSIWYG editor
$height = isset($height) ? $height : "400px";

// Set the width of the WYSIWYG editor (can be in px or %)
$width = isset($width) ? $width : "98%";

// Set to desired permission level (based on user role permissions settings)
$permissions = "edit_document"; // Set $permissions = ""; to allow full public access

// Check to see if $username was passed to the snippet and authorize if logged in
