Can anyone please save me from going insane with this nagging issue?
I'm trying to create a featureset of farms that are purely "Good practice" (Status =3 or Good=1). Here's my featureset of farm issues where farmcode (farm identifier) is not unique.

I'm trying to select farms that ONLY have Status=3 or Good =1 for each FarmCode grouping. Sometimes a FarmCode will be unique, sometimes multiples depending how many issues there are on a farm.
Cheers for any pointers,
Jonathan
