How do you access leaderboard from a different script?

I already have a savable leaderboard. Its all good.

Now, I am making a daily reward system. It is working, but it won't reward the player.

Cash is not working.

This is the cash part of my leaderboard

local cash = Instance.new("IntValue",stats)
    cash.Name = "Cash" 

This is the daily reward script

local reward = possibleRewads[math.random(1,#possibleRewads)]
game.ReplicatedStorage.ShowDailyReward:FireClient(player,hourWait,reward)
            local connection
            connection = game.ReplicatedStorage.ClaimReward.OnServerEvent:Connect(function(triggeringPlayer)
                if triggeringPlayer == player then
                    print("Reward Claimed")
                    player.leaderstats.cash.Value = player.leaderstats.cash.Value + reward
                    DataStore:SetAsync(player.UserId.."-dailyReward",os.time())
                    connection:Disconnect()
                end
            end)
