user access based on field content

[sirtemplar]

first of all, happy new year!

i have a runtime database that i would like to share on our network. the thing is i would like to grant database access (ADD, DELETE, EDIT) to users based on field content. for example:

i have a field called: COUNTRY, with a value list of countries.

- i want to grant USER1 (with his own password, of course) VIEW ALL but ADD, EDIT, DELETE only if country is U.S.

- i want to grant USER2 (with his own password, of course) VIEW ALL but ADD, EDIT, DELETE only if country is U.K.

- i want to grant USER1 (with his own password, of course) VIEW ALL but ADD, EDIT, DELETE only if country is ITALY

and so on. is this possible? thanks.
