I've just had a quick glance and I can say that you have some good normalization in place, so well done!
I will just point out two things:
1. In the Relationships I noticed you made them all OUTTER JOINs. This shouldn't be so. You should avoid Outter Joins in the Relationships window and if you need an Outter Join just do it in a query.
2. The
SumAll field should not be a field in your table. It can be calculated in a query.
This is just my 2 cents
I don't have much time to go into too much detail.
