You don't take advice well, it appears. Charles Hooper gave you a solution to this very situation with another query (missing data) by suggesting, rightfully so, to use an outer join and even provided an in-line view to join to.

Your 'example' has the correct numbers? Or is this merely an indication of HOW you'd like the output to appear? Saying it's 'all wrong :-)' says nothing of what IS wrong or what the 'correct' output should be.
