Installation on PHP

OK. i'm am having some serious issues.

1: Are all the files required? I did not upload the _docs and _samples directory. I'm assuming these are not needed to get this to work. i have a folder called admin, which holds all the fckeditor.* files. inside the admin folder is a folder called editor. This holds all the files in the editor directory. Is this the minimum installation requirements?

2: According to this heiarchy, what do I need to change in my files to get this to work? The installation page didn't include much information about this.

I really need to get this to work. It seems this is one of the wysiwyg editors that works for IE and Mozilla.

All I get on my page is a big gap between the top of my page and the Submit button. What am I doing wrong? I've included the fckeditor.php file, and this is my code for the instance:

        <?php
        // Automatically calculates the editor base path based on the _samples directory.
        // This is usefull only for these samples. A real application should use something like this:
        // $oFCKeditor->BasePath = '/FCKeditor/' ;
        // '/FCKeditor/' is the default value.
        $sBasePath = $_SERVER['PATH_INFO'] ;
        $sBasePath = substr( $sBasePath, 0, strpos( $sBasePath, "../" ) ) ;

        $oFCKeditor = new FCKeditor('details') ;
        $oFCKeditor->BasePath    = $sBasePath ;
        $oFCKeditor->Value        = '$aboutdetails' ;
        $oFCKeditor->Create() ;
        ?>
