I'm looking to find the Player while being inside a global script & mouse function?

Hi, What I am trying to do is locate the player so that I can adjust the leaderboard values inside the global script, What i am going to show you works in a local script, but does not work in a global script because It wont find the player, I have tried to add a playeradded function but it does not work... please someone help! I am relatively new at scripting.. Please! What this script is doing is targeting a part in workspace that has values. once the parts value need is met, i would like to add the created value to the leaderstats. Currently this script is sitting inside the tool (I have to use a tool, no touch functions)

local Players = game:GetService("Players")
 local block = game.Workspace.Part
 local hitz = game.Workspace.Part.hits.Value 
local hitzn = game.Workspace.Part.hitn.Value
local spawntime = 5 
local tool = script.Parent
tool.CanBeDropped = false 
local stats = localPlayer.leaderstats
local Iron = stats.Doubloons.Value
tool.Equipped:Connect(function(mouse)
    mouse.Button1Down:Connect(function()
        if mouse.Target == block then
                hitz = hitz + 1
            if hitz >= hitzn then 
                hitz = 0
mouse.Target.Transparency = 1
mouse.Target.BrickColor = BrickColor.Black()
mouse.Target.CanCollide = false
game.Players.LocalPlayer.leaderstats.Iron.Value = game.Players.LocalPlayer.leaderstats.Iron.Value +1
wait (spawntime)
block.Transparency = 0 
block.CanCollide = true
block.BrickColor = BrickColor.Blue()
            end
            end
    end)
end)
