I've made a very simple gun script that when Mouse.Target.Parent has a humanoid inside of it, it fires a remoteevent that causes that humanoid to be damaged. If I were to equip the tool, the gun works completely fine. But when I unequip and reequip the gun whenever I fire I get an error that states "This Mouse is no longer active." If someone could help me that would be greatly appreciated! Thanks!

Local script inside of the tool:

local MaxAmmo = 5
local Ammo = MaxAmmo
local Reloading = false
local Player = game.Players.LocalPlayer

script.Parent.Equipped:Connect(function(Mouse)
	Mouse.Icon = "rbxasset://textures/GunCursor.png"
	
	local function Reload()
		Reloading = true
		Mouse.Icon = "rbxasset://textures/GunWaitCursor.png"
		wait(2)
		Ammo = MaxAmmo
		Reloading = false
		Mouse.Icon = "rbxasset://textures/GunCursor.png"
	end
	
	script.Parent.Activated:Connect(function()
		if Ammo > 0 and not Reloading then
			Ammo = Ammo -1
			if Mouse.Target.Parent:FindFirstChild("Humanoid") then
				game.ReplicatedStorage.TakeDamage:FireServer(Mouse.Target.Parent.Humanoid)
			elseif Mouse.Target == nil then
				print("Didn't shoot at a brick")
			end
		elseif Reloading == false then
			Reload()
		end
		print(Ammo)
	end)
	local Input = game:GetService("UserInputService")
	Input.InputBegan:Connect(function(Key)
		if Key.KeyCode == Enum.KeyCode.R and Reloading == false and Ammo ~= MaxAmmo then
			Reload()
		end
	end)
end)

Server script:

game.ReplicatedStorage.TakeDamage.OnServerEvent:Connect(function(player, SpecHumanoid)
	SpecHumanoid:TakeDamage(20)
end)
