Hi

Is it possible to include a frequency function to a COUNTIFS function?

Im trying to count how many deliveries a driver has made in a day by using a sheet that contains multiple jobs with information such as site delivered to.
The problem I have is my COUNTIFS is counting all jobs that have been delivered by a driver on a particular day even if they have all gone to the same customers address.
I need it to include a frequency function on column D to just count the individual customers sites he delivers too.

=COUNTIFS(ACOL_All!F:F,71003,ACOL_All!J:J,$B6)

F column is the drivers ID "71003"
J column is the Delivery Date ( B6 is the Date )
D column is the Customers ID

any help would be much appreciated.
