installation problems

i am trying to install a php version of fckeditor on site im working on. i am using a function to create it as follows

function fWriteWYSIG($vNews){

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

$oFCKeditor = new FCKeditor('new-news');
$oFCKeditor->BasePath = '/functions/fckeditor/';
$oFCKeditor->Value = $vNews;
$oFCKeditor->Create();

}

this is the correct directory and everything however all i get is a page not found.

the directory is like follows

location of the install folder:
{site address}/test/admin/functions/fckeditor

location of the php file to display the editor
{site address}/test/admin/add.php

according to the documentation all that is required to run the editor or to get it to at least diplay.

1. Install it
2. Put the code from the above function on the page you would like the editor to display
3. change he paths to match the location of the editor files.

i have done all of that yet it does not show up, unless my paths are wrong?

//Basic information//

I am using firefox on a G5
I have php 5.1.4 installed on my server
the sample pages all show up fine on my server!

can anyone help me with this Thanks in advanced
