Submit Variables with fckeditor

Hello,

i am using the following script to get data into a php-variable.

<form action="eintragen.php" method="post">
<?php
$oFCKeditor = new FCKeditor('FCKeditor1') ;
$oFCKeditor->BasePath = '/fckeditor/' ;
$oFCKeditor->Value = $teaser;
$oFCKeditor->Height      = 700;
$oFCKeditor->Width      = 1000;
$oFCKeditor->Create() ;
?>
<input type=hidden name="id" value="<? echo $row->id; ?>">
    <br>
    <input type="submit" value="Submit">
  </form>

My Problem:

I am not able to get the variable id (which has a value in this script) to the next script named "eintragen.php".

How do i get the id-value from this fckedit-script to the next script.

Tnx

Sebastian
