Let me put it to you this way: I have two Format IDs in the table, with four different Attriutes attached to them. For FormatID 34, it is attributes 12,15, 19, and 25. For FormatID 49, it is attributes 12, 15, and 27. I want to search so that I get all FormatIDs that have AttributeIDs of 12 AND 15 AND NOT 27. FormatID34 has 12, and 15 and not 27 so matches my desired query, FormatID 49 has 12, AND 15, AND 27 so does not match my desired query. That is what I meant by AttributeId=12 and AttributeID=15, and why I only want 34 as my answer. It is the FormatID that matches the critera of the query.

Thanks,
