<< Why do you need javascript? >>
Good question, but I have no satisfactory answer. I was just
modifying "one I made earlier" (the only one) which happened to work

here and feel a completely fresh start is going to be the best. I
have arrived here straight from Visual Basic and am finding things
a lot different.
