'this.LinkedField.value' is null or not an object
fckeditorcode_ie.js
Line: 32
Char: 333

DESCRIPTION:
I just downloaded fckeditor and installed this on my machine running wamp. (* see below for system info ) I followed the instructions to install, created my own index.php. Ran the page in mozilla, works fine. Ran the page in IE (Beta 8) and it comes up with the above error. Not sure if this will be the same issue with ie7 or not.

Again, works fine in Firefox 3.0.5, But not in IE Beta 8. I do not have ie 7 to test on, but this seems like a common issue.

Configuration:
FCKeditor 2.6.3
PHP 5.2.5
Apache 2.2.6
Windows XP Professional


PLEASE HELP!


here is basic code used in my index.php when error is occurring:

<?php
include_once ('editor/fckeditor_php5.php');

if(isset($_POST['FCKeditor1'])) {

echo $_POST['FCKeditor1'];
}

$self = $_SERVER['PHP_SELF'];

echo "<form action='$self' method='post' target='_blank' ";
$oFCKeditor = new FCKeditor('FCKeditor1') ;
[color=#000080]$oFCKeditor->BasePath[/color] = 'editor/' ;
$oFCKeditor->Value = '<p>This is some <strong>sample text</strong>. You are using <a href="http://www.fckeditor.net/">FCKeditor</a>.</p>' ;
$oFCKeditor->Create() ;
echo "<input type='submit' value='submit'";
echo "</form>";
