Thank you, Peng Yi-fan

but incase there is no contract with the level 5, it will not be shown.
I would like to see:

level   amount
1       34
2       0
3       18
4       986
5       0

I could add it in the application, but I try to do it within the Query.

btw. the right join I mentioned, doesn't work.

Has someone another idea?

Thank you!

Jay
