Hi,
For information I have now solved my problem. The first is linked with what I deem as a fault with alfresco. If you have a reference to a file in the current directory, either an image or a script include file, when you try and view that html file in alfresco it cannot find the file, even if you reference the file ./filename. If you locate any include files in a subdirectory alfresco picks up the file and the display works.
The other problem is one of my mistake and sloppy html. Alfresco is unforgiving of sloppy html and forces you to write correct html. This is a good thing and £ signs should be written as £ and & signs as & this way there will be no ambiguity when displayed on foreign browsers.
