Remote Event Issue? Database Not Saving IntValue

My Local Script Inside Screen Gui " Testing " https://i.gyazo.com/dd2417159cc577ed4a0850adb7fdd9cd.png

Inside local script " UpgradClick" - The mouse button down and up are the only code that are associated with give player a cookie...the upgrades add cookies per click....at baseline with no upgrade when the decal cookie image is clicked it gives player 1 cookie....

Whats Inside My Server Script Service ( https://i.gyazo.com/7a165e7345dffa90379fe08a77dc5890.png)

Inside Script " leaderboard"

local datastore = game:GetService("DataStoreService")
local ds1 = datastore:GetDataStore("CookiesSaveSystem")

function savetablefunc(player)--a table is much more efficient for saving
    local savetable = {
        cookies = player.leaderstats.Cookies.Value,
        rebirths = player.leaderstats.Rebirths.Value
    }
         return savetable
end


game.Players.PlayerAdded:Connect(function(player)

    local clone = script.leaderstats:Clone()--here we clone the files over
    clone.Parent = player

    local save = savetablefunc(player)
    local savedstuff = ds1:GetAsync(player.userId)
    function datapull(player,save) -- here we pull the saved data into the ints we cloned
        player.leaderstats.Cookies.Value = savedstuff.cookies
        player.leaderstats.Rebirths.Value = savedstuff.rebirth
    end
        datapull(player,save)
end)

function savedata(player) --this is just the function to call on leaving 
    local save = savetablefunc(player)
    ds1:SetAsync(player.userId,save)
end

game.Players.PlayerRemoving:Connect(savedata)-- here we save the data on player leaving, you dont need on change its wasteful in most cases
