I have a report and I'm trying to use expressions to calculate the weighed average between 2 columns.
My report structure looks like this:
My users select a year and then the [Pvm] -column gets into 2 columns.
The Sidotut and the summing are then also in 2 columns.
I'd like to do an expression like this in the Vuosipaikat -column:
=First(Sum(Fields!F_FactCount.Value)) * (7/12) + Last(Sum(Fields!F_FactCount.Value)) * (5/12)
So I'd like to multiply the first [Pvm] -column by 7/12 and the second [Pvm]-column by 5/12 and show the sum of these two values.
This is how my report looks after processing:
How can I manage this with expressions?
The expression above doesn't seem to work...
