Calculating an average in a matrix

Hello,

 

I'm having trouble doing something that at first glance seems quite straightfoward. I have the following table:

 

 

 

Each value is the total sum calculated from the data for the respective category and date. I would like to have an extra column containing the average for the last 12 moths but when i try to do it il always ends up adding 12 extra columns with the average for each month. If it works properly the values should be 2,9 for WIP and -1,4 for UI.

 

Any clues on how to achieve this?

 

Thanks
