Create a tool that can increase an existing leaderboard's value?

Title. I want to make a tool that, when clicked, increases an exsisting leaderboard through a script (not local). I tried to start one on my own, but It didn't work without using a local script.

For some reason, when I use a LocalScript, the two leaderboards called don't match.

Leaderboard Script:

game.Players.PlayerAdded:Connect(function(player)
     local leaderstats = Instance.new("Model")
     leaderstats.Name = "leaderstats"
     leaderstats.Parent = player

     local money = Instance.new("IntValue") --We create a new IntValue
     money.Name = "Cash" --this is the name you want the leader-stat to be when it shows up in-game.
     money.Value = 0 --this is the value of money the new player starts out with. To change this, you can add some more code (shown later)
     money.Parent = leaderstats -- Set the money object as a child of the leaderstats object.
 end)

Tool Script:

game.Players.PlayerAdded:Connect(function(player)
	
	local tool = script.Parent
	
	tool.Activated:Connect(function()
		player.leaderstats.Cash.Value = player.leaderstats.Cash.Value + 1
	end)
	
end)

Thanks in advance!

For first, your leaderstats script do not contains any errors. In your Tool script use a Server Script and put this code:

local player_name = script.Parent.Parent.Parent.Name -- Find player with ServerScript.
local player = game:GetService("Players"):FindFirstChild(player_name) -- Find the player with name.
local leaderstats = player:FindFirstChild("leaderstats") -- Find leaderstats
local cash = leaderstats:FindFirstChild("Cash") -- Currency item.
local cash_for_add = 1 -- Money for player earn
local tool = script.Parent -- Tool location

tool.Activated:Connect(function() -- On click with Mouse in tool
	if player and leaderstats and cash then
		cash.Value = cash.Value + cash_for_add -- Gives the money
	end
end)

Hope it helped :)
