FCKeditor not showing

I have built a cms for a client using FCKeditor and PHP.
The client doesn't see anything where the editor show be seen.

He is using xp sp2 and IE7 with avg (i see it perfectly fine)

This is the code I used

include("../FCKeditor/fckeditor.php") ;

       
               $oFCKeditor = new FCKeditor('FCKeditor1') ;
               $oFCKeditor->BasePath = '../FCKeditor/';
               
               $oFCKeditor->Width  = '75%' ;
               $oFCKeditor->Height = '400' ;
               
               
               $oFCKeditor->Value = stripslashes($content) ;
               $oFCKeditor->Create() ;
