Using the sample below, I am looking for a way how to count the number of rows in the table in the previous group. My report is setup using a Matrix and a table (“Tablix3”) in the data region of the matrix.
The column groupings are called “DayOfTheWeek” and “AMPM”.
In the area with the blue box around it, I need the PM group to count the number of rows in “Tablix3” for the AM group on that day, which is 2. When the value is greater than 1 I will use expressions to alter the background colour accordingly as the bottom right pink background shouldn’t be there.
I am using SSRS 2008.

Unfortunately, no. You have to do it in the query.
