Yep, this works great. Just what I was looking for! But, just as soon
as I got it working, I started changing it.
I noticed that if I don't specify an "action=" term for the Form that
the response comes right back to the index() function. I actually like
that for two reason. First it lets me use one set of exception handling
code for my entire application. I don't have to wrap multiple
functions. Second it means the code to return the next web page only
has to be called from one place whether a form is being processed or
not. Anyway, I'm pretty happy with the result. I especially like how
my code has been simplified while adding the ability to upload files.
The only thing I lost was the ability to use cgitb. Now it reports the
location where I call the cgitb method. Oh, well.
I'm not sure if that will make sense. Here's what my sample app looks
like now for what it's worth.

P.S. If life was fair I'd be sending you a pile of cash now. You
solved my problem while other people were telling me to visit the local
library. Well, maybe just this once, life can be almost fair. Where can
I send the money? PayPal?
