i got the email notification that you filled in the form. the file was available by ftp. I edited the php file to save files with a combination of the number and the email addresses of the person filling it out. for some reason though I mis coded it and spaces are getting added... i thought I put something in to trim out spaces/ extra characters but that apparently didn't happen. I did get an email with a link to the fdf you created... it does work beautifully...
also I got this response back from support regarding installing PDFtk... ello,

I'd be happy to clarify!
We don't support the installation of any third party software, so I
really couldn't tell you what would need to be done specifically, but
from what I've found online here's info on how to install (we run on
Debian Linux servers): http://www.accesspdf.com/pdftk/#packages
That should get you set, but if you have any specific questions or issues
while installing, feel free to reply.
