top 3 values and corresponding attributes

[#1]

Product	Source	Destination	Cost	Cost 2	Total Cost
Handbag	A	A1	0	5	5
Handbag2	B	B1	10	10	20
Handbag3	C	C1	20	15	35
Handbag4	D	D1	30	10	40
Handbag5	E	E1	40	20	60

Right now, I'm using the above example where I'm using =FirstSortedValue(Source, [Total Cost],1)

Is there any way that if my data had 0 as one of the cost, not to include it as the cheapest source?

For example, the cheapest source would be B, C, and D.

Thanks for your help!!
