How to have the ammo not duplicate per players ?

Hey so as the title says i need to fix this script i know it is a little bit messy and its a big one but i really need help, basically everytime when you shoot/fart it - 1 ammo but when some players join like lets say its 4 total players it will - 4 ammo not 1 for the player why is it that.

Local Script

local remoteEvent = game.ReplicatedStorage:WaitForChild("FartEvent")
local input = game:GetService("UserInputService")

local debounce = false

local equiped = false

local ui = script.Parent:WaitForChild("FartUi"):Clone()

local plr = game.Players.LocalPlayer
local plrGui = plr:WaitForChild("PlayerGui")

local ammoleft = plr:WaitForChild("Farts")
local rolls = plr:WaitForChild("Rolls")
local reloading = script.Parent:WaitForChild("Reloading")


script.Parent.Equipped:Connect(function()
	equiped = true
	ui.Parent = plrGui
end)

script.Parent.Unequipped:Connect(function()
	equiped = false
	ui.Parent = nil
end)

local function updateGui()
	if not reloading.Value then
		ui:WaitForChild("Bg").MainFarts.HowMuchLeft.Text = ammoleft.Value
		ui:WaitForChild("Bg").MainFarts.texthowleft.Text = "X" .. rolls.Value
		
		wait(1)
		ui:WaitForChild("Timer").Text = "Butt Fart Timer: 10"
		wait(1)
		ui:WaitForChild("Timer").Text = "Butt Fart Timer: 9"
		wait(1)
		ui:WaitForChild("Timer").Text = "Butt Fart Timer: 8"
		wait(1)
		ui:WaitForChild("Timer").Text = "Butt Fart Timer: 7"
		wait(1)

		wait(1)

		wait(1)

		wait(1)
		ui:WaitForChild("Timer").Text = "Butt Fart Timer: 2"
		wait(1)
		ui:WaitForChild("Timer").Text = "Butt Fart Timer: 1"
		wait(0.5)
		ui:WaitForChild("Timer").Text = "Butt Fart Timer: 0"
		ui:WaitForChild("Bg").MainFarts.HowMuchLeft.Text = "Reloading..."
		wait(1)
		ui:WaitForChild("Bg").MainFarts.HowMuchLeft.Text = ammoleft.Value
	end
end


local function toggleReload()
	if reloading.Value then
		ui:WaitForChild("Bg").MainFarts.HowMuchLeft.Text = "Reloading..."
	else
		ui:WaitForChild("Bg").MainFarts.HowMuchLeft.Text = ammoleft.Value
		ui:WaitForChild("Bg").MainFarts.texthowleft.Text = "X" .. rolls.Value
	end

	updateGui()
end

input.InputBegan:Connect(function(input, gameProcessedEvent)
	if gameProcessedEvent then return end
	if equiped == true then
		if input.KeyCode == Enum.KeyCode.F then
		if not debounce then
			debounce = true
				
				remoteEvent:FireServer(plr)
			wait(10)

		end
