Welcome to the community, Chris! :grinning_face_with_big_eyes: This kind of logic is beyond the scope of Airtable’s native features. To pull this off, you (or someone you hire) will need to either write some custom code using Airtable’s API to match clients to products and add the links between the [Clients]
and [Products]
tables (guessing names), or perhaps use an integration service like Zapier or Integromat to do the job. If you would like some help in either case, let us know.
