Hello, for http://www.wowhead.com/quest=28808/fear-no-evil you need to use interactwit... (and use option "accept dead target"?).
And sometime, same quest have several ID (like your quest: 28813, 28809, 28806, 28810, 28812, 28808, 28811), to avoid to create one wrobot quest by quest id (wow class for your quest), you can add all id in one wrobot quest
