Peter, You’re welcome.
While I appreciate that you are trying to cut down on unnecessary emails (as per emailcharter.org - interesting read), it is appropriate to include the list in your responses, especially one indicating that a solution has been found, so that others on the list stop thinking about how they could help, and so that a person reading the archived list messages can feel confident that the suggestions were worthwhile. :-) NNTR -Sterling On Feb 20, 2015, at 3:20PM, Peter Rowat <pe...@pelican.ucsd.edu> wrote: > Thank you both for your help, my problem is solved.
