Hi,
I have a relational model and I'm trying to show trend per quarter, if I select prior year last 12 months. 
Current output:
 
              ProdQuant1 % of Growth Trend 
2012Q3         65             5%           +5%
2012Q2         60             5%           +5%
2012Q1         55             5%           +5%
2011Q4         50             --%           --%
The problem I'm having is I need to compare the 2011Q4 with 2011Q3 and also capture that trend as well. Any thoughts how to filter 15 months but show only last 4 quarters trends in a relational model? 
Desired output: 
              ProdQuant1 % of Growth Trend 
2012Q3         65             5%           +5%
2012Q2         60             5%           +5%
2012Q1         55             5%           +5%
2011Q4         50             5%           +5%             Assuming the 2011Q3         45             --           --
Thanks,
RK
			
			
			
				Conditionally hide the contents of 2011Q3 in the layout of the list?
