Hello Otland,

I'm trying to modify my current Quentin NPC so he is capable to sell all blessings. I suppossed that i could add the piece of code that Henricus has and it would work. I was wrong.

This is the part i added:
Lua: 
local function creatureSayCallback(cid, type, msg)
    if not npcHandler:isFocused(cid) then
        return false
    end
    local player = Player(cid)
    local totalBlessPrice = getBlessingsCost(player:getLevel()) * 5 * 1.3

    if msgcontains(msg, "myass") then
        npcHandler:say("Do you want to receive all five available blessings - for " .. totalBlessPrice .. " gold?", cid)
        npcHandler.topic[cid] = 7
    elseif msgcontains(msg, "yes") then
        if npcHandler.topic[cid] == 7 then
            if player:getBlessings() == 5 then
                npcHandler:say("You already have been blessed!", cid)
            elseif player:removeMoneyNpc(totalBlessPrice) then
                npcHandler:say("You have been blessed by all of five gods!, |PLAYERNAME|.", cid)
                for b = 2, 6 do
                    player:addBlessing(b,1)
                end
                player:getPosition():sendMagicEffect(CONST_ME_HOLYAREA)
            else
                npcHandler:say("Come back when you have enough money.", cid)
            end
        end
    end
    return true
end

This is complete script of Quentin now:
Lua: 
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

local function creatureSayCallback(cid, type, msg)
    if not npcHandler:isFocused(cid) then
        return false
    end
    local player = Player(cid)
    local totalBlessPrice = getBlessingsCost(player:getLevel()) * 5 * 1.3

    if msgcontains(msg, "myass") then
        npcHandler:say("Do you want to receive all five available blessings - for " .. totalBlessPrice .. " gold?", cid)
        npcHandler.topic[cid] = 7
    elseif msgcontains(msg, "yes") then
        if npcHandler.topic[cid] == 7 then
            if player:getBlessings() == 5 then
                npcHandler:say("You already have been blessed!", cid)
            elseif player:removeMoneyNpc(totalBlessPrice) then
                npcHandler:say("You have been blessed by all of five gods!, |PLAYERNAME|.", cid)
                for b = 2, 6 do
                    player:addBlessing(b,1)
                end
                player:getPosition():sendMagicEffect(CONST_ME_HOLYAREA)
            else
                npcHandler:say("Come back when you have enough money.", cid)
            end
        end
    end
    return true
end

You should provide the error or outcome if any, I didn't bother with your other code because you are trying to see if the callback function is working and this modified version of your callback will determine just that.
Lua: 
local function creatureSayCallback(cid, type, msg)
    if not npcHandler:isFocused(cid) then
        -- npc does not have your attention
        print("npc does not have focus")
        return false
    end
    local player = Player(cid)
    -- check for the player
    if player then
        -- now you can get the player's level
        local totalBlessPrice = getBlessingsCost(player:getLevel()) * 5 * 1.3
        if msgcontains(msg, "myass") then
            npcHandler:say("Do you want to receive all five available blessings - for " .. totalBlessPrice .. " gold?", cid)
            npcHandler.topic[cid] = 7
        -- check for the response and the state
        elseif msgcontains(msg, "yes") and npcHandler.topic[cid] == 7 then
            if player:getBlessings() == 5 then
                npcHandler:say("You already have been blessed!", cid)
            elseif player:removeMoneyNpc(totalBlessPrice) then
                -- 1-5 not 2-6
                for b = 1, 5 do
                    -- there is only 1 argument for this method
                    player:addBlessing(b)
                end
                -- make sure the blessings were added
                if player:getBlessings() == 5 then
                    npcHandler:say("You have been blessed by all of five gods!, |PLAYERNAME|.", cid)
                    player:getPosition():sendMagicEffect(CONST_ME_HOLYAREA)
                else
                    -- since they weren't added check how many blessings the player has
                    npcHandler:say("blessings count "..player:getBlessings(), cid)
                    player:getPosition():sendMagicEffect(CONST_ME_POFF)
                    return false
                end
            else
                npcHandler:say("Come back when you have enough money.", cid)
            end
        end
    else
        -- player wasn't created
        print("player doesn't exist")
    end
    return true
end

If the script isn't executing at all then you most likely have a clerical error rather than a syntax error.

There is no error nor outcome. Noc simply doesnt answer yo that words, only the ones added by keywordhandler. The same piece of code is working on another NPC(i cant post here complete Henrius npc because of lengh)

Looks like never goes into callback
