Hi friends i need a summon npc.

He have to say that:
Player: Hi
Npc: Hello |PLAYERNAME| I can obtain you a trainer for 300 gold pieces.
Player: Yes

And then the npc summon a Training Monk next to player and take 300 gold pieces of the player, can it be posible?

Not sure but i tried:

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
function creatureSayCallback(cid, type, msg)
	local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid
	
local p = getPlayerPosition(cid)
local monster = "Trainer"

if(msgcontains(msg, 'hi') or msgcontains(msg, 'hello')) then
			npcHandler:say("Hello |PLAYERNAME| I can obtain you a trainer for 300 gold pieces.", cid)			
			talkState[talkUser] = 1
elseif(msgcontains(msg, 'yes') and talkState[talkUser] == 1) then
		if(doPlayerRemoveMoney(cid, 300)) == true then
		doSummonMonster(cid, monster, p) 
	else
		npcHandler:say("Sorry, You dont have 300 gold pieces dont try to steal from me.", cid)
			talkState[talkUser] = 0
			end
			return true
			end
