Data bases, localScript, and more stuff?

Hey, i cant use roblox studio :/ Well... only right now, but could you test this script for me?

ThE ScRiPt

local player = game.Players.LocalPlayer
local mouse = player:getMouse()
local gun = script.parent

gun.equipped:connect(function()
       print ("Tool was equiped!")  
       mouse.Icon = "rbxassetid://358948941"
end

Just add a tool to the starter pack and test it pls. Also use a localScript. Then tell me if the mouse icon changed. Thank you. (also tell me trought an answer, cuz i want reputacion :/ you dont rly have to do so, only if you want...)
