I'm hoping somene can help me with my problem. I have few thousand rows of
data we create a large report from each month in Excel. We have now been
asked to add in a table which does distinct counts with multiple criteria. I
have added in a consise version below.

How can I create a formula which will fill in the results in the table below
to achieve the answers I've manually added in?
