anne:I hope I never gave the impression i was interested in point-scoring.I shall help you as tactfully as possible without,I hope,incurring the wrath of those purists who regard all assistance as helping to cheat!Otherwise we might just as well tear our hair out,each in his/her little corner,as I did years ago,where the words "computer" & "forum" were still quite foreign to my ear!It seems very easy to be seriously misunderstood online:I'm learning that gradually here.Good luck anyway!
