RunningValue In Matrix

Hello, I was wonder if it is possible to have a RunningValue per row on a
matrix? I want to Sum a number onto itself and show in each columnfor the
first row and reset for the second row and start all over again. I am going
to use conditional statements to control what value is being summed based on
the rowgroup I am at, but that number will have to sum onto itself for every
column in each row.
Ie. 38, 76, 114, 152, 190 in first row
second row: 38, 76, 114, 152, 190
These are based on the variable Fields!WC_TOTALS_DIVIDEND_ROUNDED.Value
Thanks,
BJYes reporting services literally provides a runningvalue function
called runningvalue. In your case runningvalue(Sum(Fields!
Wc_TOTALS_DIVIDEND_ROUNDED)). Put it in the data field of the matrix.
Make sure to use the appropriate column group.
