game.Players.PlayerAdded:Connect(function(player) local stats = Instance.new("Folder") stats.Name = "leaderstats" stats.Parent = player
local Strength = Instance.new("IntValue") Strength.Name = "Strength" Strength.Value = 0 Strength.Parent = stats
local Strength = Instance.new("IntValue") Coins.Name = "Coins" Coins.Value = 0 Coins.Parent = stats end)
