Hi all,
I just want to Freeze editing rights for specific field by some email-id's.
I have list of sme email-id's.
So how can I achieved this in apex?
Your solution would be appreciated.

I have a Picklist named as "No of persons " which contains 1,2,3,...etc values.
I also have one multipicklist which contains name of persons.
so if i select 2 as no of persons then i want to restrict users to select exactly 2  values from multipicklist.
how to do this with validation rule or formula?
