Lua Chance system

[Fire Element]

I wanted to put a chance this script:

function onUse(cid, item, frompos, item2, topos)

	local n = math.random(10, 100)
	doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, "You received "..n.."0k.")
        doPlayerAddItem(cid, 2160, n)
	doSendMagicEffect(getPlayerPosition(cid), CONST_ME_MAGIC_GREEN)
	doRemoveItem(item.uid, 1)
	return true
end

Example:

90% chance = 10.000 ~~ 30.000gps
80% chance = 35.000 ~~ 50.000gps
etc...

Thanks!

local rand = math.random(1,100)
if(rand == 10) then--1% chance
---------------------------------
or:
if(rand >= 50) then--50% chance.. etc u get the thing...

Best way to do this is using a 'table' and 'loops'.

local t = {
	[1, 10] = {, },
	[11, 20] = {, },
	[21, 30] = {, },
	[31, 40] = {, },
	[41, 50] = {, },
	[51, 60] = {, },
	[61, 70] = {, },
	[71, 80] = {, },
	[81, 90] = {, },
	[91, 100] = {, }
}

function returnPercentageValue()
	local r = math.random(1,100)
	for i, k in pairs(t) do
		if r >= i[1] and r <= i[2] then
			return math.random(k[1],k[2])
		end
	end
end

Edit:
I added it to your script, just in case you had problems doing it yourself:

local t = {
	[1, 10] = {, },
	[11, 20] = {, },
	[21, 30] = {, },
	[31, 40] = {, },
	[41, 50] = {, },
	[51, 60] = {, },
	[61, 70] = {, },
	[71, 80] = {, },
	[81, 90] = {, },
	[91, 100] = {, }
}

function returnPercentageValue()
	local r = math.random(1,100)
	for i, k in pairs(t) do
		if r >= i[1] and r <= i[2] then
			return math.random(k[1],k[2])
		end
	end
end	
function onUse(cid, item, frompos, item2, topos)
 
	local n = returnPercentageValue()
	doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, "You received "..n.."0k.")
    doPlayerAddItem(cid, 2160, n)
	doSendMagicEffect(getPlayerPosition(cid), CONST_ME_MAGIC_GREEN)
	doRemoveItem(item.uid, 1)
	return true
end

Be sure to add the amount range in the empty parts in the table:
Example:

[1, 10] = {1, 5},
