Hi @Mike_Coghill
If the input in your “client name” field in your “order” table is the same in the input in the primary field of your “client” table (eg 2 x “single line text” field), then you can change the “client name” field into a linked record field and it will link automatically. If a client name doesn’t exist in your “client” table, it will make a new linked record.
Does that help in any way?
