hello there.
I would like to ask again your expert help.
I would like to use formula to sum up specific number cells incase other two cells criteria met.
My excel sheet contain from several hundred maybe few thousand rows. also some blank ones.
I have attached example of my sheet.
So you can see I have like item block where customers have their orders. INT means it is orders. So what i would like is summery in each month how much X customer order only if INT number exists at column before the customer name.
But please check the attached photo i think it tells more about it what i want.
Thank you for your support.
