Attempt to index nil with 'leaderstats' Even though they exist?

So i'm making a machine that converts your resource to money at a tick rate of every second. The issue is that when the tick rate is 4 per second, and your starting amount is 30, you get -2. Now, to combat this, I made this script:

local plr = script.Parent.Parent.Parent.Parent
if plr and plr:FindFirstChild("Owner") then
	plr = plr.Owner.Value
end

script.Parent.Changed:Connect(function(v)
	print("The change of amountHolding is: "..v)
	if script.Parent.Value < 0 then
		plr.leaderstats.Money.Value += math.abs(script.Parent.Value)
		script.Parent.Value = 0
	end
end)

I've tried everything. If you know why I get the error please answer

Answer explain more of your setup but looking at the script it might be line 10 the issue. becuase what are you referring to by doing script.Parent.Value = 0 also this script should be in serverscriptservice

Here's the issue why you get that error on line 1 you use plr as an object of some sort not a player. local plr = script.Parent.Parent.Parent.Parent Then on line 9 you use the plr now as a player plr.leaderstats.Money.Value += math.abs(script.Parent.Value) Try this instead

local Players = game:GetService('Players')--added player service
local Player = Players.LocalPlayer--gets the player who activated the script
local plr = script.Parent.Parent.Parent.Parent
if plr and plr:FindFirstChild("Owner") then
    plr = plr.Owner.Value
end

script.Parent.Changed:Connect(function(v)
    print("The change of amountHolding is: "..v)
    if script.Parent.Value < 0 then
        Player.leaderstats.Money.Value += math.abs(script.Parent.Value)--Changed it to Player
        script.Parent.Value = 0
    end
end)

Hope this helps!!
