    Craig - very promising, but try adding these to the sample data set:

    UNION ALL

    SELECT 2426, 2341 UNION ALL

    SELECT 2341, 1200

    Abu Dina - are these two additional rows valid data, and if so, can you extend the data set please? I think it will help folks if there are more groups and perhaps a few rows where there are no associations at all.
