How to set up the database for a comments system

[James_Vador]

Thanks for your reply, you will find here below some screenshots of my database and the workflow used to store comments, my issue is that i don’t know how to do to have the book title in the comments data type

I have set up a group with information like author, title …etc.
I have created a multiline input feedback caption and a “submit button”

In the workflow of the button i created a new things for “comments” data type and i linked it to the “feedback data field”. The feedback are stored in the comments database but i don’t know how to do for the “book title” which is linked to “book” datatype

I hope it is clear, do not hesitate if you have additional questions.

Regards
