Hi alucardfair.
Many thanks for your reply.
I've been doing some investigation of my own and have discovered that (as you said) it depends what type of serves you site is on. Then there was something else about the server being enabled to ... well it got a bit too complex and even when I phoned my host/s they didn't help much. They just pointed me to some help files. Useless was a word that came to mind!
Anyway, I have uploaded the .jad file and the .cod files to one of my web sites and it works.
All I can guess is that the servers there must be enabled with what ever is required.
I thank you for taking the time, cause not many others have.
