4 KudoZ points awarded for this answer. Comment: "Thank you very much Danielash, Klaus, Volkmar and Transdave. Your suggestion was perfect Klaus, to which the many agrees bear testimony! Don't worry about the duplicate answer, Transdave, that has happened to me by accident on occasion too. There is a hide button in the lower right-hand corner of your answer box that you, as the answerer, can use to make your answer invisible if you so desire. I apparently hit the send button for an answer three times yesterday and my answer appeared in triplicate - I just hit the button on the last two and they "vanished". "
