That's an extremely weird set of requirements. What is it,
some kind of anti-captcha, proving that you're *not* a
human?

If the numbers are correct, there must be something wrong
with the way you're submitting the form.

Maybe the site is expecting some cookies or header values
that you're not sending?

Are you able to submit a result successfully by hand
using a browser? If so, you might be able to use Firefox's
debugging facilities to capture the exact response being
sent, including headers and cookies.
