Reverse a Measure from another measure

Hi,

I am trying to do a cross sale. Where whatever value comes in the first column needs to be in reverse orders.

I have only 2 rows. 

In the column below for Cross_Sale column I should get :

Row 1 :103

Row2 : 51

Not sure why it is taking the "total" into consideration.

Here is my formula:

Cross_Sales = 

VAR RANK_desc =
	RANKX (	
		ALLSELECTED (crop_master[CROP]),
		[Increase_SALES_BOTH_CROPS],
		,
		asc
	)
return
	CALCULATE (
		([INCREASE_SALES_BOTH_CROPS]),
		TOPN (
			RANK_DESC,
			SUMMARIZE (
			   ALLSELECTED (crop_master[CROP]),
			   crop_master[CROP],
			    "TOTAL GOOD", [INCREASE_SALES_BOTH_CROPS]
			),
			[crop], DESC
)
)	

 Thanks,

Ritesh
