I would like to help you, but unfortunately what your are asking seems more complicated then simple coding ... Based on what you described, I think you will need to create a visual interface for your clients before you can even start implenting your editor ... I mean, how are you setting up your editor so that clients can choose a page to edit??? did you create an interface that pulls and displays the pages in a specific clients folder??? Did you create an edit function so that the editor will know which page it is pulling and which page it is saving??? Is what you are creating requires authentication to access??? Will this be setup online so your clients can access it the editor anywhere, or is it just for intranet access only???

This is why Adam ask you if you had done any ASP coding because what you are asking requires some fairly advance knowledge .... 

Sorry I can't be any help...
