Hello!
I wanted to have NPC like, for example Cipfried from real tibia, who is healing a player when his hp is lower than 65.
But when player (having hp <65) says 'heal' to him, then NPC just says the text and doesn't heal him.
In my console I get this:
Code: 
[Error - Npc interface]
data/npc/scripts/heal.lua:onCreatureSay
Description:
(luaGetThingPosition) Thing not found

[Error - Npc interface]
data/npc/scripts/heal.lua:onCreatureSay
Description:
(luaDoCreatureAddHealth) Creature not found
Here is my script for this NPC (texts which NPC has are in Polish :P):
Code: 
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


-------------------------------------Healing Part------------------------------
function healCreature(cid, message, keywords, parameters)
    if(getCreatureHealth(cid) < parameters.maxheal) then
        position = getCreaturePosition(npcHandler.focus)
        doSendMagicEffect(position, 12)
        local healHP = parameters.maxheal - getCreatureHealth(cid)
        doCreatureAddHealth(npcHandler.focus,healHP)
        npcHandler:say('Wygladasz naprawde zle, pozwol ze cie wylecze.', cid)
    else
        npcHandler:say('Nie wygladasz az tak zle, ' .. getCreatureName(cid) .. '. Pomagam tylko w awaryjnych sytuacjach. Mozesz zwiekszyc ilosc swojego zycia dzieki jedzeniu.', cid)
    end    
    return true
end

function healCreatureNoMsg(cid, maxheal)
    if(getCreatureHealth(cid) < maxheal) then
        position = getCreaturePosition(npcHandler.focus)
        doSendMagicEffect(position, 12)
        local healHP = maxheal - getCreatureHealth(cid)
        doCreatureAddHealth(npcHandler.focus,healHP)
        npcHandler:say('Hello, ' .. getCreatureName(cid) .. '! Wygladasz naprawde zle. Pozwol ze cie wylecze.', cid)
    end    
    return true
end


function farewell(cid, message, keywords, parameters)         return npcHandler:defaultFarewellHandler(cid, message, keywords, parameters) end

keywordHandler:addKeyword({'heal'},     healCreature, {maxheal = 65})
keywordHandler:addKeyword({'help'},     healCreature, {maxheal = 65})


npcHandler:addModule(FocusModule:new())
