Hi. We need to see the code/query you are running before we can give you any form of answer to your question; please post the code along with the field and table metadata (the names of the fields involved, their types, and an indication of which are primary and which are foreign keys).

In posting questions on this site it is expected that posters will provide enough detail so that the volunteers who give of their time freely to answer those questions do not waste their efforts trying to guess what the question is about. Please help us to help you by giving us more detail to work on.
