At one stage in my quest, the player is asked to recover the Ink Container from Arlington (MS15ink). I can successfully use getitemcount in dialog to verify that the player possesses the the ink container and skip that stage, but the same test when used in the quest script does not seem to function.
(Player.getitemcount MS15Ink > 0)
Am I missing something about how GECK counts quest items in inventory or do my problems lie elsewhere?
