Here a sum formula
SUM(
SELECT(
Deliveries[DeliveryCharge],
AND(
([DateDone] >= [_THISROW].[BeginDate]),
([DateDone] < [_THISROW].[EndDate])
)
)
)
Same thing but with a Product() function like in Google appsheet
PRODUCT(
SELECT(
Deliveries[DeliveryCharge],
AND(
([DateDone] >= [_THISROW].[BeginDate]),
([DateDone] < [_THISROW].[EndDate])
)
)
)

I pretty not understanding why a simple function like doesn’t exist!
