Value is not a valid member or Tool | Banknote | [Jojo Games] ?

Hello, I am coming again to ask for help from your community since I am stuck on something easy, yet I cannot find the solution.

I created a script that allows you to add money when you click, however nothing happens, I have this error when I click.

12:25:59.515 - Value is not a valid member of Tool 12:25:59.516 - Stack Begin 12:25:59.517 - Script 'Workspace.maxime66410.Banknote.LocalScript', Line 9 12:25:59.517 - Stack End

So I'm totally stuck, I can show you the script (not finished).

BankNote Script (LocalScript or Script also does not work) :

local Money = script.Parent



Money.Equipped:Connect(function(Mouse)
    Mouse.Button1Down:connect(function()

                local tag = game:GetService("Players").LocalPlayer:FindFirstChild("Money").Value
                local player = game.Players:FindFirstChild(Money.Value)
                local amount = math.random(150,10000)
                player = player + amount


    end)    
end)

First Version of my script :

local Money = script.Parent
local tag = script.Parent.Tag



Money.Equipped:Connect(function(Mouse)
    Mouse.Button1Down:connect(function()
        if tag.Value ~= nil then
            if game.Players:FindFirstChild(tag.Value) then
                    local player = game.Players:FindFirstChild(Money.Value)
                    local amount = math.random(150,10000)
                    player = player + amount
            end
        end 
    end)    
end)

And Version final of my scripts but i don't have error, but still no money to add.

local Money = script.Parent
local tag = game:GetService("Players").LocalPlayer
local addMoney = game:GetService("ReplicatedStorage").Logic.AddMoney



Money.Equipped:Connect(function(Mouse)
    Mouse.Button1Down:connect(function()
        if tag ~= nil then
            if game.Players:FindFirstChild(tag) then
                local player = game.Players:FindFirstChild(tag)
                local amount = math.random(150,10000)
                player:FindFirstChild("Money").Value = player:FindFirstChild("Money").Value + amount
                addMoney:FireServer(player,tag)
            end
        end 
    end)    
end)
