Help Needed on Complicated Query

[boooney]

Hi-

I have a database that has a number of projects and suppliers for these
projects. Each project has several contracts being supplied by several
suppliers.

I have a suppliers form with a contracts subform. What I want to do is
create a subform inside the contracts subform where i will be able to add and
edit invoices that have been billed against that contract. The matching data
is:

Same project, supplier, contract

Here is the relationship diagram:

I need help forming the SQL statement. I'm sort of lost by the whole thing.

Thanks very much.
