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.
To flatten a PDF is to transform a interactive PDF into a non-interactive PDF.
If, in your process, after you've inserted all the information you wanted in your form, you transform your Interactive PDF in a flat PDF you'll be able to insert and extract pages in Adobe Pro (or other versions).
