Group by Row, then right click on the group row, add row (inside below).. At corresoponding place write the expression like = Fields!Jan.Value - Fields!Feb.Value Let me know if you find any difficulty.!SqlUser2011

No answer?

But we dont want the difference between months. We want the difference between years. The row difference!
