Check if the access_token parameter is set and print it, and then check it in the debugger.
To call FQL
This is based on general letters for months, in particular a, e and u. You can make strpos out of this to fit these.
SELECT name, birthday, email, uid FROM user WHERE uid in (SELECT uid2 FROM friend WHERE uid1 = me()) AND (strpos(lower(birthday),"a") >=0 OR strpos(lower(birthday),"e") >=0 OR strpos(lower(birthday),"u") >=0) ORDER BY birthday_date
This should print all zeros since null does not contain letters (by definition, null, not the letters themselves)
