Lua Function creatureSayCallback and how to get a variable's value?

[waqmaz]

I try to write a bank script on my own, but the only thing I do not know how to do is how to get a value from a variable that player has writed?
Here is the code:

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
local talkState = {}
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) local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid

    if not npcHandler:isFocused(cid) then
   
        if msg == 'hi' then
            npcHandler:addFocus(cid)
        else
            return false
        end

    else
        money = tonumber(money) -- integer
        money = math.abs(money)
   
        if (msg == 'deposit '..money) then
            if getPlayerMoney(cid) >= money then
                selfSay('You have successfully deposited '..money..' gold points. Your account balance is '..getPlayerBalance(cid), cid)
            end
        end
   
        if msgcontains(msg, 'bye') then
            npcHandler:releaseFocus(cid)
        end
   
    end

   
    return true

end

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)

-- npcHandler:addModule(FocusModule:new())

The script doesn't see the money variable. It's nil even if i write "deposit 10".

if (msg == 'deposit ' and getCount(msg) > 0) then
money = getCount(msg)
  if getPlayerMoney(cid) <= money then
  selfSay('You have successfully deposited '..money..' gold points. Your account balance is       '..getPlayerBalance(cid), cid)
  end
end

Bad answer, even with this function does not work.

local function getCount(s) -- -1 domyślnie
    local b, e = s:find('%d+')
    return b and e and math.min(4294967295, tonumber(s:sub(b, e))) or -1
end

k, works, ty.

     if msgcontains(msg, 'deposit '..getCount(msg)) then
            money = getCount(msg)
            print(money)
        end
