Why isn't this working, it says the scales(Like body height scale) is not there?

function Playersize(player)
	local Sv = 5
	local humanoid = player.Character.Humanoid
		humanoid.BodyHeightScale = Sv
		humanoid.BodyWidthScale = Sv
		humanoid.BodyDepthScale = Sv
		humanoid.HeadScale = Sv
end
local player = game.Players.LocalPlayer	

game.ReplicatedStorage.Events.Transformation.OnServerEvent:Connect(function(player)
	Playersize(game.Players.Brockanthony10)
end)
