Hi, can you elaborate?

[newbie_sm]

I need a wildcard formula to calculate aggregate sum sales where 

For Product B, in months Jan-Apr 2022, the value should calculate as 29000 and in Jan-Apr 2023 is 10000

while for Product A, the values are different from each month.

How do I sum these together?
