I need to use the SUBTOTAL function within a formula that uses SUMPRODUCT AND COUNTIF. The formula I'm using does a count of records in a list, eliminating duplicates. Now I need to use the SUBTOTAL function along with it to calculate the count of records, eliminating duplicates, when I filter on one of the fields. The formula I'm currently using looks like this:
=SUMPRODUCT(1/COUNTIF(i6:i13,i6Li13))
Thanks a lot
=SUMPRODUCT(1/COUNTIF(i6:i13,i6Li13))
Thanks a lot
