I'm a new user of Filemaker. I met a problem by using it for some data in my lab. We have several diffenrt fiels now, and one of them is a master file. I want to build a realtionship between this master file and another file, which is to relate one field(A) of the master file to two fields(B & C) in that file. And we need only one match, (A match : or (A match C).

How can I do this? Thanks a lot.

You're not exactly clear. Please explain more clearly just exactly what you want. For example, are you looking to match A with B+C, or with either B or C?
