Update Knack.com javascript/json code for new knack app.

99% of the work is already done. I had this done earlier for a [login to view URL] database app. I scrapped it, and created a new one. What I want done: When a user submits a form, "Add Practice Date," I need all of the "Members" connected to the "Group" connected to the just created "Practice Date" to have a record created in the "Practice Attendance" table connected to the just created "Practice Date" record. Click button, creates a new Practice date. App sends user to the "Practice Date Details" page where there is a table with all the "Practice Attendances" connected to that new practice date. The JSON scrip you'll write will create a "Practice Attendance" record for every "Member" connected to the "Group" connected to the "Practice Date." I want this done on 1 form. In one place, when clicking "Submit" form, the code will run, inserting a new record for each "Member" associated with that "Practice Date''s" "Group," into the "Practice Attendance" table. The included code worked on 3 different "Scenes." This only needs to work on one "Scene/View." I will add the person working on this as a shared DEV on the [login to view URL] website so you can see the scenes, views, etc, and update the code to run, as well as give you a test login to try it on the live site.
