Here is my NPC
I keep getting the console error lua:4 attempt to index global 'npcHandler' <a nil value>
can not load script
So how do I make it so he sells and buys stuff, and also does quests and messes with storage values

I figured it out, here is the npc if anyonelse wants to use such a thing:
You just have to put the coding for the quest first, and the coding for the shop beneath it, but it all has to be together in a certain way (sorry I dont know much about coding)
Code:
local
shopModule = ShopModule:new()
npcHandler:addModule(shopModule)
shopModule:addBuyableItem({'letter'}, 2597, 8, 1,'letter')
shopModule:addBuyableItem({'parcel'}, 2595, 15, 1,'parcel')
shopModule:addBuyableItem({'label'}, 2599, 1, 1,'label')
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
function creatureSayCallback(cid, type, msg)
if(not npcHandler:isFocused(cid)) then
return false
end
local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid
