I have created a select list for Profile2 account in Drupal 7. In the allowed values list I have added some value. Now what I would like to do is programmatically update the values in that list (add, delete or update). I don't want to use form_alter as I want these updates committed to the database. My problem is I can't seem to find where these values are stored in the database or how to pull those values from Profile2, update them and then save them.
I have Googled high and low on this particular issue and can't find an answer on how to do this. I hope someone can help me out.
