Editor does not display

Hi,

i have install the editor (complete) here: http://relikt.ch/ckeditor
When i start this script http://relikt.ch/ckeditor.php does not show the editor (with the right path).
This script i have installed:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title>A Simple Page with CKEditor</title>
        <!-- Make sure the path to CKEditor is correct. -->
        <script src="ckeditor/ckeditor.js"></script>
    </head>
    <body>
        <form>
            <textarea name="editor1" id="editor1" rows="10" cols="80">
                This is my textarea to be replaced with CKEditor.
            </textarea>
            <script>
                // Replace the <textarea id="editor1"> with a CKEditor
                // instance, using default configuration.
                CKEDITOR.replace( 'editor1' );
            </script>
        </form>
    </body>
</html>

Can someone help me?
