How to Attach a File to a PDF Document in Foxit PhantomPDF

I agree with J Chak. I have followed both your example as well as the step by step from the user's manual. Neither seem to work. Guess I'll just have to scan my document to accomplish getting a complete document.

Video is confusing, as you are attaching PDFs to a PDF. Also using inefficient ways to get into Attachment pane. Also it doesn't show how to provide a link in the document itself to open the attachment, as users of the PDF won't know that there is an attachment to view in the Attachments pane.
