why are my debounces not working properly in my aiming scripts?

i have 2 tools in my starterpack, and when i rightclick, i want the fov to get smaller, then back to 70 when clicked again. when i right click it works, but when i switch to another tool while aimed in, it no longer works... i have no idea why, but im pretty sure it's because of my debounces.

here is one of my tools aiming scripts: (pretty much the same for both)

bat.Equipped:Connect(function()
	equipped = true
	aiming = false
	plr.Character.Humanoid.CameraOffset = Vector3.new(.6,1.7,0)
	bat.Equip:FireServer(plr)
	mouse.Button2Down:Connect(function()
		if equipped == true then
		if aiming == false then
			aiming = true
	workspace.CurrentCamera.FieldOfView = 40
	plr.PlayerGui.CrossHair.Aiming.ImageLabel.Visible = true
	plr.PlayerGui.CrossHair.NonAiming.ImageLabel.Visible = false
			print(aiming)
		else
			aiming = false
	workspace.CurrentCamera.FieldOfView = 70
	plr.PlayerGui.CrossHair.Aiming.ImageLabel.Visible = false
	plr.PlayerGui.CrossHair.NonAiming.ImageLabel.Visible = true
	print(aiming)
		end
		bat.Unequipped:Connect(function()
		equipped = false
			aiming = false
	workspace.CurrentCamera.FieldOfView = 70
	plr.PlayerGui.CrossHair.Aiming.ImageLabel.Visible = false
	plr.PlayerGui.CrossHair.NonAiming.ImageLabel.Visible = true
	print(aiming)
	bat.Unequip:FireServer()
		end)
		end
	end)
end)
