Many thanks, Fred. Your comments were extremely helpful in that they make sense, but I don't understand them well enough to actually turn them into action steps - which suggests I am trying to do things I should not be (yet), hence my 'fishy' code.
I'll go back and start from scratch on a tutorial, then attack this project fresh later.
