Saw this info:

We have a client that wants to have an HTML form to enter a value, then a calculation would be done in our web script and something (?) would be sent to the PP HTML process to merge the computed total into a PDF template that would create a "final version" for online viewing and electronic signing (maybe running through the Http server process again) and sending the final PDF by email to the customer and my customer (taxing agency). Does your demo work, since it doesn't given the "How-to" test it on the link above.
