What I've done so far:
- Republished the main form (minus the secondary set of fields that needs to be saved into the 2nd doc library)
- Created a content group for the secondary set of fields, was confused whether I just switch the existing doc library's setting to Allow management of Content Type)
basically, I have no idea what I'm doing haha I've been trying to figure it out by instinct. When I was republishing the main form, when it gets to the Fields window, I was assigning the main field into a Site Column > Content Group I created). BUT I'm not sure where and how to locate those in the end since they're not the same fields as the 2nd doc library contents.
What have I done?!#!#! :D
