Problem in the NPC dialogue 5375

[N.I.G.H.T.M.A.R.E]

Hello all go my question is very easy and simple, but is a doubt very important.
Well we know how to create an NPC just add the codes in dialogs.cs and insert an ID, this ID will be the same in sql table of NPCs, but when I turn the server is not the NPC Honestly .. I have a doubt about the table fields npc (task0, Task1, task2 ...) I would like to know if this is what is missing to start with on the NPC decks.
PS: My source is 5375

Question:
What are the task and how do I tell my NPC?
