Hi
I've now reached the hair tearing point . I suspect I am making a fundemental error which is stopping the queries I wrote and the ones kindly supplied via this thread.
I've attached a copy of the database with 95% of the data removed in the hope that someone will see what I've done wrong.
If it's back to the drawing board so be it but I can't for the life of me see what I've missed.
thanks
Ian
