Assigning a value to a player who just joined isnt working?

game.Players.PlayerAdded:Connect(function(player)
	    if player.Data.Stand.Value == 1 then
		local random = math.random(2,31)
		player.Data.Stand.Value = random
	end
end)

    

i seriously think im making a really simple mistake but im not sure what itis

Do player:WaitForChild("Data"):FindFirstChild("Stand").Value

I think that should work.
