 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 CWeek 1 100 300 350Week 2 550 350 700Week 3 250 550 450Total 900 1200 1500Weekly Avg 300 400 500Last Week Var -50 150 200Max 550 550 700Variance -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.

 Name the cells so they are easy to remember e.g. MonthTotal and then refer to those cells directly in an expression:`=ReportItems!MonthTotal.value`

 I have tried that but a matrix doesn't allow it. I get the following error message - "Report item expressions can only refer to to other report items within the same grouping scope or a containing grouping scope."

 You can use multiple groups in the same tablix that aren't nested within each other. That way your 3 month average doesn't need to be in a second tablix. You can also add totals or variances in cells that are outside any grouping at all yet still within the same tablix.

 Excuse my ignorance, but does this work in SQL 2005? If so how do i add another line in my matrix below the total line to to the calcualtions.Thanks in advance.

 My apologies I didn't see that it was for BIDS 2005. I've logged on to one of my old SQL Server 2005 machines and luckily it had BIDS 2005 installed on it so I could try.Wow I forget how painfully bad that version was. The jump to 2008 is light years ahead. I can't work out how to do what I was suggesting in 2005, I'm sorry.You may have to do something in the SQL to make it work, like make use of pivot/unpivot and cube/rollup.

 Thanks for checking. I ended up creating a summary table in sql and will populate summary data there for calculations and then report.I appreciate the time and effort.

 I think that you've done it the best way possible with 2005.
