Thanks again guys
I'll take a look at the other suggestions over the next couple of days. I had a deadline to meet today, hence the rush to get it sorted. That deadline has now passed and the spreadsheet results have been printed and distributed. Next deadline is in a month's time, so maybe i'll have it tidied up by then
Cheers
Jem

There is another that states that this has already happened.”... Douglas Adams 1952 - 2001
