Sorry, first post with no topic.

Given 3 tables:
Table Operations(Op)
Op_ID, Op_Name,...


Table TravelerHEADER(TravH)
TravH_ID, TravName, Part_ID,...


Table TravelerDETAIL(TravD)
TravD_ID, TravH_ID, Op_ID, TravOrder,...

How can I retrieve the OP RecordSet
associated with the subset of TravD records
given a single TravH_ID?

That is to say:
There are a finite set of travd records that relate to a singular travh record... for each of those travd records I want the related Op record.

Stumped again,
