Path to listViewer.php

Hi, there.

I've integrated CMS Builder into my client's site without any problems, and it's been used to add content:

http://www.satoa.com/membersList.php.

I'd like to get the search engine working and the documentation states that I should use the following tag:

<form method="POST" action="/path/to/your/listViewer.php">

How do I find out what the actual path is to listViewer.php on this particular server? I can't find a file with this name.

Thanks!
