I have a matrix reporting data by week by location. The matrix works great for this. The challenge, however, is I want to take my total from the matrix and provide a 3 month average - easy enough to do with another matrix. Then i need to take the last weeks data (matrix 1) compare it to the 3 month average (matrix 2) and calculate a variance. Then show the max value from the 3 months and calculate a variance against the last weeks data.

for example

location A location B location C

Week 1 100 300 350

Week 2 550 350 700

Week 3 250 550 450

Total 900 1200 1500

Weekly Avg 300 400 500

Last Week Var -50 150 200

Max 550 550 700

Variance -54% 0% -35%

Any suggestions on how to accomplish the bottom calculations when you can't use fields from various matrices in a report?

Thanks in advance.
