I think I understand that.  Those are the exact steps that I've
identified for myself as well and have been trying to do off and on over
the past month (spare time is hard to come by!).  It's the mechanics of
such with which I need help.  I've spent a good deal of time with
apparently the wrong the magic incantations.

If someone wouldn't mind taking a look at the script, I think it'd make
it clear where my trouble is.  It takes about 5 seconds to run on my
machine, and I've tried to help it highlight exactly what I'm missing.

Thank you,
