I'm catching up on the weekend's tutor messages.
import cgitb; cgitb.enable()
That spits errors to the web page which is great for debugging cgi
scripts.
I think you need
print "Content-Type: text/html\n\n"

Thats not the point (sorry).
when all the values are provided in the form (no excetion is raised) it
runs as expected!
The point is when one of the values "ano", "conta" is missing in the
form, I want the error message to be shown on the browser, and the
script to stop running.
When there is an exception, the script actually stops running, but no
message is sent to the browser.
