Help with quests

I need some help with making some quests. This is what I'm trying to do: the main quest is to defeat a bandit leader and bring his helmet back to the mayor of the town. I am trying to make a cut-scene that activites the quest. I want it so that when my captain hero talks to the mayor, the mayor gives him the quest. Also, I have three optional quests I am having trouble with. The first one is where I have to retrieve a wedding ring that was stolen from a farmer. I want the farmer to give the captain the quest and when the captain talks to the farmer again after getting back the ring the farmer takes the ring (the ring is removed from the captain's inventory) and the farmer gives him a ring of protection (+1). The next sub-quest is where a merchant wants me to get his stolen merchandise back from highwaymen. After getting the merchant's goods back and returning to the merchant, I want the merchant to thank the hero, and remove the goods from the hero's inventory and reward the captain with slippers of agility. The last optional quest is where my hero talks to a woodsman who asks the hero to retrieve his hunting horn from a few gnolls (three to be exact). The woodsman, after the captain gets his hunting horn back, removes the horn from the captain's inventory and gives the hero a healing potion.

Well, what portion of settings up these events are you having trouble with? It's sounding like you want somebody else to do all the work for you.

I just need someone to tell me what I need to do to get the quests working right.

at map int, you would create a quest and mark it as undiscovered. Use the Quest trigger to create it, give it a icon, and description. Then set a variable = to the last created quest so you can refer to it later.

When you want to reveal the quest, just do so with Mark Quest as Revealed.
