hello

I am writing a Validation rule as -

AND(ISCHANGED( field_name ) =TRUE,
             OR(LastModifiedBy.Email!=abc@site.com',
                    LastModifiedBy.Email!='xyz@site.com'))

I want to make sure that the field can be modified by above 2 users only.

However, I don't get an Error message I have supplied in Validation Rule.

Please help.

Thanks
