I uploaded a template using the InDesign plugin. Why are all the fields missing in my master PDF?

Be sure that all the text and picture fields you tagged with the eDocBuilder plugin exist on the document area. If you have tagged text or picture boxes on the pasteboard, they will not be created as expected because PDF files and eDocBuilder have no concept of the InDesign pasteboard area. Please see point #18 in this article for more information: Tips, Tricks, and Warnings for using the InDesign Plugin, 18) Keep any tagged text and images boxes on the document area and not the pasteboard
