Hi Andy,

If no-one manages to find a solution for you right away, could you please
supply some pseudo-data from the tables you are working with. Also, which db
server application and version are you working with?

I'm sure a solution can be found, but I for one would be closer to helping
you find it if I had a better idea of the structure of the tables involved
and the data they contain.

Regards,

Murray
