Use date reference is a vlookup formula

Question

I have attached a printscreen to make it easier to understand my question.

I'm creating a supply management woorkbook. Income will refer to the purchases and outcome the resale of this purchases. Because there will be price variations, I'm looking for a formula to insert on Outcome Total Price that will return the purchase price of the item sold to deduct from the total value of my stock.

I don't know if it's possible to use a second reference on vlookup formula, like to return the price of product A with the condition that it has to be before the date 19/09/2016.

假设在任何给定的一天中任何给定产品的条目不超过一个，并且假设数据按时间顺序排列，请在F3中尝试此操作并复制下来

=IF(E3>0,SUMPRODUCT($D2:D$3,--($A2:A$3=A3),--($B2:B$3=MAX($B2:B$3))),"")
