Hello
I want to thank everyone for their kind replies to my questions and also for the invaluable information I've gleaned trawling the forums and finding nuggets contained in posts, often from a while ago, that are so very helpful.
Special thanks to Pam, UKsearch, Guy , Geoffers, Jan - sorry if I've missed anyone but I do appreciate everyone's help.

Sorry, everyone, I posted this in 'Lancashire' by mistake - should have engaged my brain before using my keyboard.
