Hi,
I'm trying to sum each months visa purchases. The data is in three columns: date,value and payment type.
I can't get this formula to work:-
{=SUM(IF(AND(Purchases!C6:C999>DATE(2009,12,28),Purchases!C6:C999<DATE(2010,1,29)),IF(Purchases!K6:K999="Visa",Purchases!H3:H999)))}
It's returning a value of 0 (and if that were true I'd be delighted!)
Thanks in advance.
