Carl,
you are correct - I have edited the code. I have uploaded the incorrect file by mistake. I have edited my first post to include the correct code. I had edited a couple of the field names to see if that would make any difference, but it didn't.
The DTD that it is formatted against is avaiable at

Thank you for your help
