Thank you dr b. Perhaps one day I'll be clever enough to get by without help. In the meantime, I'm grateful for all the incredible knowledge, wisdom, logic and wackiness shown by all my friends on this site. I certainly don't profit in any way from using the answers - it's just so frustrating not to know the answers after trying so hard. And sometimes just knowing the answers but not kowing why is even worse. I've finished it now, thanks to this last answer. Goodnight. I hope to 'see' you all next week.
