So i am working on a casino script and i need some help with the dice and npc

[Angel Of Death]

Alright so i need an npc that when you say hi he says would you like to roll the dice for 500 gp so you say yes he removes the gp and he says pick a number so you do so say 5 the npc then rolls the dice thats sitting on the table if the dice lands on the 5 you get 1000gp simple enough

This npc is done with 2 dices. Read the script and make it to 1 if you want. I made it with 2, it's too easy to win otherwise.

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local talkState = {}

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)
	if(not npcHandler:isFocused(cid)) then
		return false
	end

	local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid

	-- Casino --
	local winP = 25
	local cost = (getPlayerMoney(cid)/100*winP)
	local need_money = 5
	
	if(msgcontains(msg, "rules") or msgcontains(msg, "information") or msgcontains(msg, "info")) then
		selfSay("(There is 2 dices) In this betting/rolling dice game you have to get a 6 on one of the dices to win.\n Ex. I bet and roll and get 5 and 5 I will lose, but If get 6 and 5 I will win. You will always bet 25% of your total money that you have in your inventory. If you win, you will get 25% more than your bet.\n Ex. I have 100 gold coins. I have to bet 25 gold coins. If I win, I will get 125 gold coins total, else I will lose them of course. (You need to have atleast ".. need_money .." gold coins).\n Interested now?", cid)
	end
	
	if(msgcontains(msg, "roll")) then
		if(getPlayerMoney(cid) >= need_money) then
			selfSay('Are you sure that you want to roll the dice and bet {'.. math.ceil(cost) ..'} gold coins? Ask me for the {rules} if you don\'t know them.', cid)

		else
			selfSay('Sorry, you don\'t have enough gold. You need to have atleast '.. need_money ..' gold coins.', cid)

	elseif(msgcontains(msg, 'yes') and talkState[talkUser] == 1) then

					selfSay("Oops, you lost {".. math.ceil(cost) .."} gold coins. That was ".. winP .."% of the money you bet. Your number was: ".. diceN1 .." and ".. diceN2 ..".", cid)
					doSendMagicEffect(getCreaturePosition(cid), 2)

	elseif(msgcontains(msg, 'no') and isInArray({1}, talkState[talkUser])) then

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
