Sell System Problem

[Nottinghster]

Hello Guys!

I have another problem

I'm using the Jiddo's NPC System and when I say 'sell item' the NPC asks if I want to buy the item. The problem occurs when the same item has to buy and sell.

Here is the dialog:

14:00 GOD Nottinghster: hi
14:00 Sam: Hi GOD Nottinghster. Can I do something for you?
14:00 GOD Nottinghster: sell mace
14:00 Sam: Do you want to buy 1 mace for 90 gold coins?
14:00 GOD Nottinghster: bye
14:00 Sam: Good bye and come again.

Here's an example of NPC (Sam):

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

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)
	if(npcHandler.focus ~= cid) then
		return false
	end
	
	-- Inicio Sam by Rodrigo (Nottinghster)
	if msgcontains(msg, 'magic plate armor') then
	npcHandler:say('WOW! Do you really want to sell me a MAGIC plate armor?')
	talk_state = 3
	
	elseif msgcontains(msg, 'yes') and talk_state == 3 then
	npcHandler:say('Oh, unbelievable! I would pay 6400 gold for this wonderful piece of armor. Are you still interested?')
	talk_state = 4
	elseif msgcontains(msg, 'no') and talk_state == 3 then
	npcHandler:say('Hmmm, what a pity! I am looking for such an armor since I live in Thais.')
	talk_state = 0
	
	elseif msgcontains(msg, 'yes') and talk_state == 4 and getPlayerItemCount(cid, 2472) >= 1 then
	npcHandler:say('Finally it is mine! Here is your money. Can I be of any further help?')
	doPlayerAddMoney(cid, 6400)
	doPlayerRemoveItem(cid, 2472, 1)
	talk_state = 0
	elseif msgcontains(msg, 'yes') and talk_state == 4 and getPlayerItemCount(cid, 2472) == 0 then
	npcHandler:say('Argl! You do not have one! Trying to tease me? Get lost or I call the guards!')
	elseif msgcontains(msg, 'no') and talk_state == 4 then
	npcHandler:say('Maybe my offer is too low? Unfortunately I can not bring up more money, I am just a smith.')
	talk_state = 0
	
	elseif msgcontains(msg, 'backpack') or msgcontains(msg, 'old backpack') then
	npcHandler:say('What? Are you telling me you found my old adventurer\'s backpack that I lost years ago??')
	talk_state = 5
	
	elseif msgcontains(msg, 'yes') and talk_state == 5 and getPlayerItemCount(cid, 3960) >= 1 then
	npcHandler:say('Thank you verry much! This brings back good old memories! Please, as a reward, travel to kazordoon and ask my old friend Kroox to provide you a special dwarven armor. ...')
	npcHandler:say('I will mail him about you immediately. Just tell him, his old buddy sam is sending you.')
	setPlayerStorageValue(cid, 289, 1)
	doPlayerRemoveItem(cid, 3960, 1)
	talk_state = 0
	elseif msgcontains(msg, 'yes') and talk_state == 5 and getPlayerItemCount(cid, 3960) == 0 then
	npcHandler:say('No, you don\'t have my old backpack. What a pity.')
	talk_state = 0
	elseif msgcontains(msg, 'no') and talk_state == 5 then
	npcHandler:say('What a pity.')
	talk_state = 0
	end
	return TRUE
	end
	
local shopModule = ShopModule:new()
npcHandler:addModule(shopModule)
