Exchanging NPC

[klinggels]

I made a exchange npc but i want it to give a bag with items but when i tried the npc disapeared.
Anyone can help me fix it?

Here is epic.lua :

local talk_state = 0

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 msgcontains(msg, 'epic') then
              if getPlayerItemCount(cid,2089,1) then
                    if doPlayerRemoveItem(cid,2089,1) == 1 then
                              selfSay('Here is your rewards! .')
                              doPlayerAddItem(cid,1987,1)
      <inside>
        <item id="7418"/>
        <item id="7433"/>
        <item id="6534"/>
        <item id="7424"/>
        <item id="2184"/>
        <item id="7431"/>
     </inside>
                    end
              else
                    selfSay('I am sorry then!. ')
                    talk_state = 0
              end
     elseif msgcontains(msg, 'no') then
              selfSay('Ok.. Good bye then!!')
              talk_state = 0
     end

return true
end

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())

so try:

local talk_state = 0

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 msgcontains(msg, 'epic') then
              if getPlayerItemCount(cid,2089,1) then
                    if doPlayerRemoveItem(cid,2089,1) == 1 then
                              selfSay('Here is your rewards! .')

        bp = doPlayerAddItem(cid,9774,1)
        doAddContainerItem(bp,9955,1)
        doAddContainerItem(bp,9969,1)
	doAddContainerItem(bp,6579,1)
	doAddContainerItem(bp,6528,1)
	doAddContainerItem(bp,8850,1)
	doAddContainerItem(bp,8901,1)

                    end
              else
                    selfSay('I am sorry then!. ')
                    talk_state = 0
              end
     elseif msgcontains(msg, 'no') then
              selfSay('Ok.. Good bye then!!')
              talk_state = 0
     end

return true
end

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())

And Global.lua

function doPlayerBuyItemContainer(cid, containerid, itemid, count, cost, charges)
if doPlayerRemoveMoney(cid, cost) == TRUE then
for i = 1, count do
local container = doCreateItemEx(containerid, 1)
for x = 1, getContainerCapById(containerid) do
doAddContainerItem(container, itemid, charges)
end
doPlayerAddItemEx(cid, container, 1)
end
return LUA_NO_ERROR
end
return LUA_ERROR
end
