How to check a value in the player?

I'm making a thing where i t makes a folder called Inventory inside the player and a intValue called Log and when they click this button it checks if they have 5 or more logs it prints the player name has 5 or more logs but it didnt work Instead i got a error: Players.googlpeopel15.PlayerGui.InvGUI.Frame.LogWall.PurchaseHandler:3: attempt to index nil with 'Inventory' - Client - PurchaseHandler:3 12:15:33.742

Here is Inventory adding code. (Server script in ServerScriptService)

game.Players.PlayerAdded:Connect(function(player)
    local Inventory = Instance.new("Folder")
    Inventory.Parent = player
    Inventory.Name = "Inventory"

    local Log = Instance.new("IntValue")
    Log.Parent = Inventory
    Log.Value = 0
    Log.Name = "Log"
end)

The Code that is causing errors (LocalScript in InvGUI which is in StarterGUI)

script.Parent.MouseButton1Click:Connect(function(player)
    local logamount = player.Inventory.Log
    if logamount.Value >= 5 then
        print(player.Name "Has 5 or more then 5 logs")
    else
        print(player.Name "Has less than 5 logs")
    end
end)
