They are coming from the same table, but from different records. The structure is :
A participant table (all participants)
An answer table (a list of answers)
A match table (all combination of participants)
On the participant table, I have the fields “Question 1” and “Question 2” that are linked records to the “Answers” table.
On the match table, I have a record for every possible combination (Participant 1 with Participant 2, participant 1 with participant 3, participant 2 with participant 3, etc), with the lookups you see above.
