Matrix table add year over year variance

Question

I am trying to get add a variance column to a matrix report is ssrs 2008 r2. However I am unable to create the custom code needed. I have been working with many examples online but none seem to fit what I am trying to do. Any help would be great. I am trying
to calculate the diff at a month level year over year. Like month 1 2013 – month 1 2014
I have a matrix table with three column grouping
Quarter
Month
Year
Design view of table
Quarter

and Fisc_year

Hi SQLtl,
To achieve your requirement, we can directly use expression. For more details, please refer to the following steps:
Right-click the column contains Year field to insert a column with Outside Group-Right.
Then type the following expression to the corresponding cells:
=Sum(iif(Fields!Year.Value="2014",Fields!REVENUE.value,0))-Sum(iif(Fields!Year.Value="2013",Fields!REVENUE.value,0))
Besides, we can also use custom code to achieve the same goal, please see:
