Hullo Maureen, I was thrilled to receive your reply to my query, and fortunately opened up the computer minutes before taking off for a week's holiday!! I will get in touch with you again on our return, but in the meantime, thanks a million for this information - I will work on it. We live in NZ, so there will probably be a bit more research than if we lived in the UK, but it is a challenge.
With our very best regards, and thanks again - be in touch later.
Rita
