using posted data in the textarea

I am sorry, but I can't solve this. Can someone help me please. The integration of cdeditor works now. It adds data in my database, that works fine.
But when I want to show the added data I can't get them.
In my former FCKeditor I had it like hereunder. The $be is the variable for the posted data.

<?php
include("../../fckeditor/fckeditor.php"); // includen van het bestand
$oFCKeditor = new FCKeditor('bericht'); // aanroepen van de class, de naam van je textbox
$oFCKeditor->BasePath = '../../fckeditor/'; //de root pad
$oFCKeditor->Width = '600'; // de width
$oFCKeditor->Height = '600'; // de height
$oFCKeditor->Value = $be; // de value (een standaard text in de textbox.)
$oFCKeditor->Create(); // het aanmaken
?>

I use de ckeditor like this, but this doesn't work, $be doesn't show the data:

<?php
include_once '../../ckeditor/ckeditor.php';
include_once '../../ckfinder/ckfinder.php';

$ckeditor = new CKEditor();
$ckeditor->basePath = '/ckeditor/';
$ckfinder = new CKFinder();
$ckfinder->BasePath = '/ckfinder/';
$ckfinder->SetupCKEditorObject($ckeditor);
$ckeditor->editor('bericht, $be');
?>

How can I do this. I've been searching the sample pages, and the community, but I dazzles me, and I can't find it.
I tried it with with replace, with value, but nothing works.
Can anybody give me a hint?
