straight table- expression written for a rowno

[#1]

i have a straight table in which I have made 'horizontal' under presentation tab. so for eg

1. quarter is my dimension

2. sales and rebate in my expressions

I get months in columns and other metrics in first column as shown in table.

I want a last column which gives (quarter3-quarter2) value. for this i used rowno concept and wrote in condition two expressions.

I am not getting values in last column. strange thing is for some metrics im getting n for some i dont.

Please help with this. Thanks

	Quarter1	Quarter2	Quarter 3
Netsales	3445	5678	234
Rebate	33	76	56
