Forms: presenting a user with options from a different Airtable to the form datasource

Hi all,

Scenario:

  • A user submits information in form A and form B which populate airtable A and B
  • When a user interacts with form C (with source airtable C) I want them to be able to select from what they chose in form A and form B

For the life of me, I can’t work out how to do this but it must be simple

I attached a diagram if its helpful
