Hi Paul,Case 1: if you know all 4 fields u can use valdiation rule as F1 == F2 & F2==F3 & F3==F4.Case 2: if you dont mention fields and you want check any 4 fields out off all fields in the object. Then you have to write a trigger before insert, before update. I suggest to use schema class to play with all fields with in your logic as part of comparision.Thanks.
