Hello everyone,
I’m trying to replicate a process I set up a year ago that is working well. I have a formula that opens a form for a responses table that automatically links it to the main table. The formula uses the form address and prefill, with the record id of the main table record. When I open one of those links it works perfectly. It is not editable, but shows the linked record information.

I’m trying to replicate it on a new base, but the same prefill option isn’t bringing up anything unless I make the group editable and then anyone with the form would be able to see all our records.
Here are the differences I can spot, but I don’t know how to make them match:
In my working form I see this in the group settings

The other difference is that the new form gives me this warning under Rules, which is not present in my working form, but I think that’s because I had create a filter in the past.

Any thoughts on what I might have missed? Both forms are in the Forms builder (not interface or base).
