Gun bug. Please help

Tried creating a gun. I did it, but there is a bug. So whenever you shoot the gun, it wastes 1 bullet, obviously, and when the gun has 0 bullets, it reloads of course. BUT, wheneveryou unequip the weapon and re equip it, whenever you shoot, you lose and extra bullet. Lets say the gun wastes 1 bullet when shot, i unequip, then re equip, and then the gun starts losing 2 bullets per shot? I do that again, then it starts wasting 3 bullets per shot. Here is the local script:

local mouse = game.Players.LocalPlayer:GetMouse()

local tool = script.Parent

local Player = game.Players.LocalPlayer
local Char = game.Workspace:WaitForChild(Player.Name)
local Humanoid = Char:WaitForChild(“Humanoid”)

local enabled = true
local maxAmmo = tool.Handle:WaitForChild(“maxAmmo”)
local fullammo = true

tool.Equipped:Connect(function()
local LoadHumAnim = Humanoid.Animator:LoadAnimation(script.Idle)
LoadHumAnim:Play()

local UserInputService = game:GetService(“UserInputService”)

– A sample function providing one usage of InputBegan
local function onInputBegan(input, gameProcessed)
if input.KeyCode == Enum.KeyCode.R then

  	if maxAmmo.Value < 10 and maxAmmo.Value > 0 then
  	enabled = false
  		tool.Handle.Reload:Play()
  		local LoadHumAnim = Humanoid.Animator:LoadAnimation(script.Reload)
  		LoadHumAnim:Play()
  	wait(2.2)
  	maxAmmo.Value = 10
  	enabled = true
  	

  	end
  end
  
  tool.Unequipped:Connect(function()
  	LoadHumAnim:Stop()
  end)

end

UserInputService.InputBegan:Connect(onInputBegan)

script.Parent.Activated:Connect(function()

  if enabled == true then

  		wait(.2)
  		script.Parent.Fire:FireServer(mouse.Hit.p)
  		tool.Handle.Fire:Play()
  		maxAmmo.Value -= 1

  		local LoadHumAnim = Humanoid.Animator:LoadAnimation(script.Fire)
  		LoadHumAnim:Play()

  		if maxAmmo.Value < 1 then
  			enabled = false
  			tool.Handle.Reload:Play()
  			local LoadHumAnim = Humanoid.Animator:LoadAnimation(script.Reload)
  			LoadHumAnim:Play()

  			wait(2.2)
  			maxAmmo.Value = 10
  			enabled = true
  			

  		
  	end

  end

end)

end)
