How DO I Make A Tool Add Leaderstats?

so i have been scripting for 2 weeks and my tool isnt working in game but it is in studio also can i get help adding animation?

LeaderStats Code Its Supposed To Save Data This is normal script

local DataStoreService = game:GetService("DataStoreService")

local myDataStore = DataStoreService:GetDataStore("myDataStore")

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

    local Muscle = Instance.new("IntValue")
    Muscle.Name = "Muscle"
    Muscle.Parent = leaderstats

    local data
    local success, errormessage = pcall(function()
        myDataStore:GetAsyn(player.UserId.. "-Muscle")
    end)

    if success then
        Muscle.Value = data
    else
        print("There Was A Error Saving Your Data")
        warn(errormessage)  
    end
end)

game.Players.PlayerRemoving:Connect(function(player)

    local success, errormessage = pcall(function()  
        myDataStore:SetAsync(player.UserId.."-Muscle",player.leaderstats.Muscle.Value)
    end)    

    if success then
        print("Player Data Is Saved :D")
    else
        print("There Was An Error Saving Data")
        warn(errormessage)
    end

end)

and here is my tools code this is local script

script.Parent.Activated:Connect(function()
    local plr = game.Players:FindFirstChild(script.Parent.Parent.Name)
    if plr then
        local stats = plr:WaitForChild("leaderstats")
        local Muscle = stats:WaitForChild("Muscle")
        Muscle.Value = Muscle.Value + 1
    end
end)
