Adding a country to an address in Addressbook with AppleScript

Question

Hi,
I'm stuck on a simple script to add a certain country to every contact that hasn't one in my Address Book.
This is the code at the core:
repeat with thisPerson in every person
repeat with thisAddress in every address of thisPerson
if (country of thisAddress) is "" then
set (country of thisAddress) to "My Country"
end if
end repeat
end repeat
The log however shows a 'missing value' every time I want to get the country of an address. How can I fix this?
(And how can I format code in this forum?)
Thank you for any input,
christian

That's correct - there is a difference between 'missing value' (no value recorded) and "" (an empty string).
The solution is simple - check for 'missing value' - rather obscurely, 'missing value' is an AppleScript keyword used just for that purpose:
  if (country of thisAddress) is missing value then
    set country of thisAddress to "My Country"
  end if
