An Intake Form to Feed Multiple Tables

I was wondering how I could create a single form to feed rows into multiple related tables. I found this wonderful thread which gave me the clues I needed. But I also needed a working example to make this all clear in my own head.

In case you need a working example too, here it is: One Form for Multiple Tables.


I am pretty new to Coda, so if anyone has suggestions that would improve this technique, please let me know. Thanks!
