Hi Sarah,
Great question! Within the Save & New Action Set before the Clear/New action gets executed use an Action Result to save the current Active Record ID.

Now to make sure the screen works/looks correctly we will initiate 2 Show/Hide Fields to 'SHOW' both sections:
(1) Contacts
(2) Contacts Info Details
Now that we're done with the screen-prep we are ready to pull and update fields on screen from the Cases table.
We're going to Loop the Cases table:

We will then update fields onscreen within the Loop from Row:

Give that a try and let me know if you run into any issues.
