my script:

Lua: 
local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local talkState = {}
 
function onCreatureAppear(cid)				npcHandler:onCreatureAppear(cid) end
function onCreatureDisappear(cid)			npcHandler:onCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg)			npcHandler:onCreatureSay(cid, type, msg) end
function onThink()					npcHandler:onThink() end
 
	if(msgcontains(msg, 'north gate')) then
		selfSay('Do you want to travel to the north gate for 50 gold coins?', cid)
	elseif(msgcontains(msg, 'yes') and talkState[talkUser] == 1) then
		if getPlayerlevel(cid) <= 30 then
			if(doPlayerRemoveMoney(cid, 50)) then
				doTeleportThing(cid, {x= 828, y=1137, z=7})
				selfSay('There you go!', cid)
			else
				selfSay('Sorry, you don\'t have enough gold.', cid)
			end
		elseif getPlayerlevel(cid) <= 30 then
			if(doPlayerRemoveMoney(cid, 50)) then
				doTeleportThing(cid, {x= 828, y=1137, z=7})
				selfSay('There you go!', cid)
			else
				selfSay('Sorry, you don\'t have enough gold.', cid)
			end
		else
			selfSay('Sorry, you are too high level', cid)
		end
	elseif(msgcontains(msg, 'no') and isInArray({1})) then
		selfSay('Ok then.', cid)
	end

error msg:

so this npc should be able to teleport players of level <= 30 and ask 50 GP for that.
My problem is that the NPC doesn't even talk at all.

Use (under this line: function onThink() npcHandler:eek:nThink() end)
Lua: 
function creatureSayCallback(cid, type, msg)

It's also missing more things, you use talkUser, so add this.
Lua: 
local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid
And add this under the function, so it only response when focused.
Lua: 
	if(not npcHandler:isFocused(cid)) then
		return false
	end

And this at the end of the script, for the function creatureSayCallback and to add focus on greet.
Lua: 
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())

Also don't forget to use return true and end the function.

Add this at the end of the script, under all ends.
Lua: 
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())
Also use return true above the last end, else it's only if someone says no.

In the yes line you check for talkState[talkUser] == 1, but it's not set when you say north gate.
So add this.
Lua: 
talkState[talkUser] = 1
Also, you are checking 2x for the same thing.
Lua: 
if getPlayerlevel(cid) <= 30 then
elseif getPlayerlevel(cid) <= 30 then
