I want show the total for cost at the bottom should be
((112*1537)+(222*1567)+(54*2048))/388 = 1625
Currently I'm using the following expression but its giving me wrong avg
=(SUM(Fields!Units.Value))*(Fields!Rent.Value)/SUM(Fields!Units.Value)
The expression is multiplying the total Units by a single Rent value.
(112 + 222 + 54) * (1537 or 1567 or 2048) / (112 + 222 + 54)
It should have a SUM around the Rent, but it would still be incorrect.
(112 + 222 + 54) * (1537 + 1567 + 2048) / (112 + 222 + 54)
It should sum the total Costs (Units * Rent) and then divide by the number of units for the average:
=SUM(Fields!Units.Value * Fields!Rent.Value) / SUM(Fields!Units.Value)
Which would end up as:
(112 * 1537 + 222 * 1567 + 54 * 2048) / (112 + 222 + 54)
