Display difference in a Matrix

[Gavin_Shales]

Hello,

I really stuck on something really basic. I just want to be able to add somwthing to this Matrix that shows the difference between the 2 months. I have searched the internet and forums but I can't seem to find anything.

Here is my basic Matrix that I am building so you can see my structure.

Everything is from one Data Source Table called TPL Test Pet

Really hoping someone can help. 

Regards

Gavin

I would suggest having a look at this:

You should be able to engineer measures that display your information in the rows as they are now but in the Total area show the difference.
