Here you go,

In npc/scripts/hamforsword.lua:

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
 
-- OTServ event handling functions start
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
-- OTServ event handling functions end
 
function creatureSayCallback(cid, type, msg)
    -- Place all your code in here. Remember that hi, bye and all that stuff is already handled by the npcsystem, so you do not have to take care of that yourself.
    if(npcHandler.focus ~= cid) then
        return false
    end
 
if msgcontains(msg, 'trade') or msgcontains(msg, 'ham') or msgcontains(msg, 'fire sword') or msgcontains(msg, 'sword') then
            selfSay('Would you like to trade 5 ham for my firesword?')
            talk_state = 1
 
 
        elseif msgcontains(msg, 'yes') and talk_state == 1 then
            if getPlayerItemCount(cid,[color=blue]2671)[/color] >= 5 then
                if doPlayerTakeItem(cid,[color=blue]2671[/color],5) == 1 then
                    selfSay('Here you are.')
                    doPlayerAddItem(cid,[color=red]2392[/color],1)
                end
            else
                selfSay('Sorry, you don\'t have the item.')
            end
 
 
        elseif msgcontains(msg, 'no') and (talk_state >= 1 and talk_state <= 5) then
            selfSay('Ok then.')
            talk_state = 0
        end
    -- Place all your code in here. Remember that hi, bye and all that stuff is already handled by the npcsystem, so you do not have to take care of that yourself.
    return true
end
 
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())

The NPC:

<?xml version="1.0" encoding="UTF-8"?>
<npc name="Kyle" script="data/npc/scripts/hamforsword.lua" autowalk="1" floorchange="0">
	<health now="100" max="100"/>
	<look type="63" head="20" body="39" legs="45" feet="7" addons="0"/>
<parameters>
<parameter key="message_greet" value="Hello |PLAYERNAME|. I can give you a firesword for 5 pieces of ham." />
</parameters>
</npc>

Let me know if it works,
Pazzur

        elseif msgcontains(msg, 'yes') and talk_state == 1 then
            [b]if getPlayerItemCount(cid,2671) >= 5 then[/b]
                if doPlayerTakeItem(cid,2671,5) == 1 then
                    selfSay('Here you are.')
                    doPlayerAddItem(cid,2392,1)
                end
            else
                selfSay('Sorry, you don\'t have the item.')
            end

The bold check is not needed, can be like this (shorteeerr ):

elseif msgcontains(msg, 'yes') and talk_state == 1 then
    if doPlayerTakeItem(cid,2671,5) == 1 then
        selfSay('Here you are.')
        doPlayerAddItem(cid,2392,1)
        talk_state = 0
    else
        selfSay('Sorry, you don\'t have the item.')
        talk_state = 0
    end

+ added reseting talk_state.
