I have this infopath form with 8 fields named:
Field1 Field2 Field3 Field4 etc.
How should I go to validate the form in a way that I cannot have duplicate values on those fields.
I cannot use code-behind because I dont have access to the central admin, plus a code-behind sandbox solution is too buggy for my like, keep getting random errors when publishing, using it. So I am looking for a no-code solution. I am using Sharepoint Server 2010.
