Not the same case but in the same range : how to apply a criteria on each of the duplicates ?

table t_TIR with fields strMot, IsVerbe, IsFlexion, ID (and other fields)
table t_DEF with PrimaryKey "ID" that make the link with t_TIR (1 to many), from which I extract DEF hereunder.

What I want to track :

1. one of the duplicates contains "-->" in DEF, and the value of IsFlexion = False,
   AND
2. the other duplicate has IsVerbe = True and IsFlexion = True

There could occasionally be more than two records in the duplicate : it is OK to show them as long as the conditions are fulfilled on two of these duplicates.

Kind regards,

Jean-Michel
