Hi Vamsi

Firstly, for future reference, please use the "Insert Code" option to include code in your posts as it makes it way easier to read/copy/paste for those of us who are trying to help:

Secondly: the code doesn't look well-formed to me. Pasting it into the Expression Editor it throws a syntax error:

    if(rule!AF_RULE_General_isBlank(wherecontains(cons!GCC_DSE_cons_getReadOnlyDrillStatus,tointeger(local!drill.drillStatus))),
remove(local! facilityFloors, wherecontains (false,local! facilityFloors.isActive)),
if(not(rule!AF_RULE_General_isBlank(local!drillfacilityFloors)),
local! drillfacilityFloors,
remove(local!facilityFloors, wherecontains (false,local!facilityFloors.isActive))))

    Same code, same syntax error

    Expression evaluation error: Syntax error. Details: Cannot create an identifier with zero length key:

    ...that is, this code will never work as it stands.
