itemToGive is a table which will hold the index of items depending on what is asked for
Code: 
local keywordHandler = KeywordHandler:new()

Can you please also explain what line that tell npc to take tokens from player it is this like
Code: 
if doPlayerRemoveItem(cid, tokens, itemToGive.amount) then
why itemtogive there in the local for itemtogive there is nothing... lol im confusing
Click to expand...
Lets say we asked the npc for boots of haste, itemToGive would be assigned ["boots of haste"] which is a subtable of items its is a the same thing as saying
Code: 
itemToGive = items["boots of haste"]
Now itemToGive has the same properties as the index of items["boots of haste"]

Code: 
items["boots of haste"].amount 
itemToGive.amount

Would both have the value of 10 for amount.

Code: 
items["boots of haste"].id
itemToGive.id
Would both have the value of 2195 for id.

Hmm i wonder.. could we cheat?
by changing this line
Code: 
 if isInTable(items, string.lower(msg)) then
to this
Code: 
if isInTable(items, string.lower(msg)) and msgcontains(msg, msg) then

EDIT: its doesnt work getting this shit ... when i try to get items exemple boots of haste and the error show that its callback so i mean like its stop and restart... i think

You can also do it like this.
Code: 
local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local talkState, xmsg = {}, {}

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

local tokens = 5468 -- id of tokens
local items = {
  ["boots of haste"] = {
      amount = 10,
      id = 2195
  },
  ["demon helmet"] = {
      amount = 20,
      id = 2493
  }
}

function creatureSayCallback(cid, type, msg)
     if not npcHandler:isFocused(cid) then
         return false
     end

     local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid

     local x = items[msg:lower()]
     if x then
         selfSay('Did you bring me '..x.amount..' game tokens?', cid)
         xmsg = msg
         talkState[talkUser] = 1
     elseif msgcontains(msg, 'yes') and talkState[talkUser] == 1 then
         x = items[xmsg:lower()]
         if doPlayerRemoveItem(cid, tokens, x.amount) then
             doPlayerAddItem(cid, x.id, 1)
             selfSay("Here you go!", cid)
         else
             selfSay('Sorry, you need to have atleast {'..x.amount..' game tokens} . Come back when you have them.', cid)
         end
         talkState[talkUser] = 0
     elseif msgcontains(msg, "no") and talkState[talkUser] == 1 then
         selfSay('Come back when you have enough game tokens.', cid)
         talkState[talkUser] = 0
