Sum Cumulative that restarts with if there a 0.

[eatv1000]

Good day,

I am trying to get the sum cumulative of a row but restarts if cell value is 0. What's the formula to get the Sum cumulative of product A? Column A is the name of the product and column b is the value. I don't know how to explain it but here's the example.


Product A 1
Product B 1
Product B 1
Product A 0
Product A 1
Product A 1

Sum Cumulative = 2

Shame you did not mention " Only for A " in your first message ...

I thought it was pretty obvious.
