Record level permissions in Zoho Creator; how to set

Record level permissions in Zoho Creator; how to set

I have a form which will be filled by the same person but depending on the value of a  Field (e.g. USA / Europe) the list of users who have permission to view the report changes.

i.e. User A should only be able to see fields having Field set to USA and User B should be able to see all fields. 

Can I set record level permissions of this nature in zoho creator? How do I do this?
