Hi There,

Challange:
I am currently using the following formula to count unique items inside of a database (as a columns).
=IF(COUNTIF($D$2:D2,D2)=1,1,0)
This gives me either 1 or 0 in return, I use this column in other calculations to show a base (n).

However I need this formula to act like a Subtotal formula, so when the database is filtered the calculation updates.

The database is very big so I need a way to do this without an array.

Which came first: VisiCalc or Lotus 1-2-3?
Dan Bricklin and Bob Frankston debuted VisiCalc in 1979 as a Visible Calculator. Lotus 1-2-3 debuted in the early 1980's, from Mitch Kapor.
