TFS 1.2 random reward doesnt work

[Tbol]

Hello so im trying to make a global random reward after completing a missions with this code i wrote which means 50% chance to get it
if math.random(1, 100) <= 50 then
player:addItem(6425, 1)
selfSay("You got lucky and received item.", cid)
end

and this is how full function looks like

function creatureSayCallback(cid, type, msg)
    if not npcHandler:isFocused(cid) then
        return false
    end

    local player = Player(cid)
    if not player then return true end
    
    if msg and msg == "tasks" or msg == "mission" then
        local text = "Tasks: "
        for i = 1, #tasks do
            if i == #tasks then
                text = text..""..tasks[i].name[1].."."
            else
                text = text..""..tasks[i].name[1]..", "
            end
        end
        
        selfSay(text, cid)
        return true


    elseif msg and msg ~= "cancel" then
        local TASK = nil
        
        for i = 1, #tasks do
            if isInArray(tasks[i].name, msg) then
                TASK = tasks[i]
                break
            end
        end
        
        if not TASK then return true end
        
        local playerTask = tasks[player:getStorageValue(taskStorage)]

        if TASK then
            if player:getLevel() < TASK.levelReq then
                selfSay("You must be level "..TASK.levelReq.." to start that task.", cid)
                return true
        end
    end
        
        if player:getStorageValue(taskStorage) == nil or player:getStorageValue(taskStorage) == -1 then
            player:setStorageValue(taskStorage, TASK.id)
            for i = 1, #TASK.monsters do
                player:setStorageValue(TASK.monsters[i].storage, 0)
            end
            selfSay(TASK.msg, cid)
            return true
        end

            
        if player:getStorageValue(taskStorage) ~= playerTask.id then
            selfSay("You must complete the "..playerTask.name[1].." task first. You can also {clear task}.", cid)
            return true
    
        else
            local isComplete = true
        
            for i = 1, #TASK.monsters do

-- Check if the player gets lucky for the global reward

                local number = math.random(1, 100)

if number <= 50 then

                    player:addItem(6425, 1)

                    selfSay("You got lucky and received item.", cid)

                end
