Script breaks after inserting data saving code?

Hey guys. It's my first time trying to create a game, and I've been experimenting for the past few hours, watching tutorials and all of that but I ran into a problem. I'm trying to place data saving into my game but it ends up breaking everything

Here is how the script looks before entering the Data Save code

local Players = game:GetService("Players")

local function leaderboardFunction (player)
    local leaderstats = Instance.new ("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player



    local Soil = Instance.new("IntValue")
    Soil.Name = "Soil" 
    Soil.Parent = leaderstats
    Soil.Value = 0

    local Cash = Instance.new ("IntValue")
    Cash.Parent = leaderstats
    Cash.Name = "Cash"
    Cash.Value = 0
end

Players.PlayerAdded:Connect (leaderboardFunction)


local r = game.ReplicatedStorage.Click

r.OnServerEvent:Connect (function(player)
    player.leaderstats.Soil.Value = player.leaderstats.Soil.Value + math.random(2,3)
    end)

And here is where everything breaks, The leaderboard stops working and the labels which i have for the 2 variables Soil and Cash stop working, the code for those is below

local DataStoreService = game:GetService("DataStoreService")

local myDataStore = DataStoreService:GetDataStore("myDataStore")


local Players = game:GetService("Players")

local function leaderboardFunction (player)
    local leaderstats = Instance.new ("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player



    local Soil = Instance.new("IntValue")
    Soil.Name = "Soil" 
    Soil.Parent = leaderstats
    Soil.Value = 0

    local Cash = Instance.new ("IntValue")
    Cash.Parent = leaderstats
    Cash.Name = "Cash"
    Cash.Value = 0
end

local data
local success, errormessage = pcall (function()
    data = myDataStore:GetAsync(player.UserId.."-cash")
    data = myDataStore:GetAsync(player.UserId.."-soil")

end)

if success then
    cash.Value = data
else
    print("An error occured while loading your data")
    warn(errormessage)


end)

local success, erorrmesage = pcall (function()
    myDataStore:SetAsync(player.UserId.."-cash",player.leaderstats.Cash.Value)
    myDataStore:SetAsync(player.UserId.."-soil",player.leaderstats.Soil.Value)

    if success then
        print ("Player data saved")
    else
        print ("An error occured while saving data")
        warn(errormessage)
    end


Players.PlayerAdded:Connect (leaderboardFunction)


local r = game.ReplicatedStorage.Click

r.OnServerEvent:Connect (function(player)
    player.leaderstats.Soil.Value = player.leaderstats.Soil.Value + math.random(2,3)
    end)

Here is the Console Output

16:35:06.427 leaderstats is not a valid member of Player "Players.Daki_Games" - Client - LocalScript:5

16:35:06.427 Stack Begin - Studio

16:35:06.427 Script 'Players.Daki_Games.PlayerGui.MainUI.TextCash.LocalScript', Line 5 - Studio - LocalScript:5

16:35:06.428 Stack End - Studio

When i click the error in the output it brings me to the script for "Cash"

local Lp = game.Players.LocalPlayer

while true do
    wait (0.1)
    script.Parent.Text = "????" .. Lp.leaderstats.Cash.Value

end

And the other one brings me to the script for "Soil"

local Lp = game.Players.LocalPlayer

while true do
    wait (0.1)
    script.Parent.Text = "????" .. Lp.leaderstats.Soil.Value

end

I've been stuck on this for a good time now, I've probably made a dumb mistake and I'd appreciate if anyone could help me out. Thanks
