what dir does it use?

I am using FCK editor for a CMS but I got a problem with the dir. that fck editor is in. I use the php version, but its not hard php

the page where I use it is http://localhost/nemo/editor/editsite.php
which got the this PHP:

<? 
include("FCKeditor/fckeditor.php") ;
?>

        <?
$oFCKeditor = new FCKeditor ;
$oFCKeditor->ToolbarSet = 'Default' ;
$oFCKeditor->Value = $row['tekst'] ;
$oFCKeditor->CreateFCKeditor( 'EditorAccessibility', '98%', '100%') ;
?>

this includes the file in http://localhost/nemo/editor/FCKeditor/fckeditor.php . This sounds good, and it's the way I want it...

but when the page loads it's put this file in the Iframe: http://localhost/FCKeditor/fckeditor.ht ... ar=Default

When I remove one of these 2 editors (or change the name) I got an error, and the editor wont load. What did I do wrong?
