local gifts = {
-- 1% - 10, 5% - 50, 10% - 100 , 100% - 1000
        {50, 14096, 1}, -- {percent, ID, count}
        {10, 2439, 1}
    }

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

local item = {}
local reward = 0
local count = ""

    for i = 1, #gifts do
        item = gifts[i]
        if (math.random(0,999) < item[1]) then
            reward = item[2]
            subType = item[3]
            print(reward)
                if subType > 1 then
                    count = subType ..""
                else
                    count = "1"
                end
            break
        end
    end
  
    doRemoveItem(item2.uid, 1)
    doPlayerAddItem(cid, reward, subType)
    doSendMagicEffect(getCreaturePosition(cid), 29)
    doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE,"** You get: " .. count .."x " .. getItemNameById(reward) .. " from box!")

Get 1 random item or can get more then one at once?
Is there a chance to not get any item?
@Fresh
I'm not good at combinatorics, but I think that with you script you got chance:
Item 1: 5%
Item 2: 0.95% (1% of 95%)
Lose: 94.05% (rest)
With higher item chances, it goes even worse. You need to remember about that ,when configuring script or you need to rewrite it to sum all items up to 1000 and then choose one of them (or few) by random number.
