I'd like to know how to make attachments automatically open up at the end of the form and be included in the page numbering. Is there any way of inserting them in a subform or something of that nature? Thanks.
If you want to insert pages, then you should do something like this (after filling in all the form data the end user wants):
- flatten PDF (Output ES)
- insert pages (Acrobat)
- Sign & Certify (Acrobat)
If all you want is to attach files you don't need to flat your PDF and can go right to Signing your PDF with Acrobat.
If you users don't have Acrobat then you'll need Reader Extensions (to enable the PDF to be signed) and Digital Signatures (to add digital signature fields to the PDF IF and only IF the PDF has been flattened, if it is a interactive form you can add the digital signature fields in Designer).
