I wrote an excel formulas e-book that makes learning 75 most frequently used excel formulas as simple as eating pie. If you are wondering the book is worth your investment, read these wonderful reviews the book has received from fellow excel bloggers in the community.
Jimmy on Code for Outlook and Excel:
I really like the way the e-book sticks to only the most common formulas, since those are the ones I use most often and therefore am more likely to need help with. It’s also great if you don’t know many formulas, to use as a tutorial to help you understand each function. …
Overall a very good value and should prove useful when you are stuck trying to get a simple formula to work (which is more often than you might think).

Great Chandoo. Keep it up, Looking forward more from BYOD..

With Excel 2013 the pivot table could be connected to the data model which provides a distinct count.
This will do for invoice count
=COUNTIF(F:F,H12)
Instead of
=COUNTIFS(sales[SELLER],$H12)
Excellent document. How did you make the last graphic? Witch app. Thanks for answer.
Can someone tell me what =countif(sales[date],sales[date]) is counting? The value is 19. Its found in the =SUMPRODUCT(IF(sales[SELLER]=H12,1/COUNTIFS(sales[SELLER],H12,sales[date],sales[date]),0))
Hi Chris,
=countif(sales [date],sales[date]) function is counting the unique dates in the table.

Excellent document!
Can you explain more about the calculation on Weighted consistency? More specific the small number is 0,00001 ?
How come the number should be smaller if there is more sellers?
Hi,
Not understood this formula: {=SUMPRODUCT(IF(sales[SELLER]=H12,1/COUNTIFS(sales[SELLER],H12,sales[date],sales[date]),0))}
Please explain.
Thanks.
