Hi Stefan
Thank you, email is on its way to you. Regret the docs are about 39MB in total, even zipping them saved very little, so I sent them as they were.
Update - files are too big, according to the email I've just received, so I suspect they haven't reached you. Ah well, no worries, I'll take another look over the next few days and will try the merge with other but similar files to see how it gets on.
Regards
Mike
