I need a formula that will pull items from a certain column, depending on two other criteria related to two other columns, and print out every instance that matches all of the above once and only once, and stop printing when all instances are printed. Currently have been relying on this for half of the job (printing one, and only one, instance of every unique element), but have not been able to incorporate the other two criteria: =ArrayFormula(index(RawData!$E$2:$E$500000, match(0, COUNTIFS($C$1:$C12,RawData!$E$2:$E$5000),0)))
