Why my collector script with datastore doesn't work ?

Hello everyone, I made a tycoon that records user data all the time. And as soon as a block of the dropper falls into the collector it makes me win 1 cash so I did that but it doesn't work, why ?

Database script:

local DataStore2 = require(1936396537)
DataStore2.Combine("MasterKey", "Level", "XP", "Cash")
local defaultLevel = 0
local defaultXP = 0
local defaultCash = 0

local XpToLevelUp = function(level)
    return 100 + level * 5
end

game.Players.PlayerAdded:Connect(function(player)
    --Leaderstats
    local leaderstats = Instance.new("Folder", player); leaderstats.Name = "leaderstats"

    local levelValue = Instance.new("IntValue", leaderstats); levelValue.Name = "Level"
    local XpValue = Instance.new("IntValue", leaderstats); XpValue.Name = "XP"
    local CashValue = Instance.new("IntValue", leaderstats); CashValue.Name = "Cash"

    --Get DataStore
    local levelStore = DataStore2("Level", player)
    local XpStore = DataStore2("XP", player)
    local CashStore = DataStore2("Cash", player)

    --Fonction quand le niveau et l'xp et le cash va être mise à jour
    local function updateLevel(level)
        player.leaderstats.Level.Value = level
    end

    local function updateCash(cash)
        player.leaderstats.Cash.Value = cash
    end

    local function updateXP(xp)
        if xp >= XpToLevelUp(levelStore:Get(defaultLevel)) then
            XpStore:Increment(XpToLevelUp(levelStore:Get(defaultLevel)) * -1)
            levelStore:Increment(1)
        else
            player.leaderstats.XP.Value = xp
        end
    end
    updateLevel(levelStore:Get(defaultLevel))
    updateXP(XpStore:Get(defaultXP))
    updateCash(CashStore:Get(defaultCash))

    levelStore:OnUpdate(updateLevel)
    XpStore:OnUpdate(updateXP)
    CashStore:OnUpdate(updateCash)
end)

My collector script

local DataStore2 = require(1936396537)
local collector= game.Workspace.House2.Purchases.Conveyer.collector
local leaderstats = game.Players.Player.leaderstats.Cash
local function onTouchEnded(part)
    for k, player in pairs(game.Players:GetChildren()) do
        local xpStore = DataStore2("Cash", player)
        xpStore:Increment(1)
        print("Touch ended: " .. part.Name)
        part:Destroy()
    end
end

while true do
    wait(0.5)
    recolteur.Touched:Connect(onTouchEnded)     
end
