How to make a game pass that makes a player twice their size?

Hello fellow developers and friends! I am interested as to how I can correctly make a game pass make a player twice their size in game if they own the game pass. I inserted a script into ServerScriptService. Here is what I wrote:

local MS = game:GetService("MarketplaceService") local ID = 10136218

if MS:UserOwnsGamePassAsync(game.Players.LocalPlayer.UserId, ID) then wait(1) game.Players.LocalPlayer.Character.Humanoid.HeadScale = 2 game.Players.LocalPlayer.Character.Humanoid.BodyWidthScale = 2 game.Players.LocalPlayer.Character.Humanoid.BodyHeightScale = 2 game.Players.LocalPlayer.Character.Humanoid.BodyDepthScale = 2 end

It does not work and the output does not output anything? If anyone could help that would mean a life saver to me! Thanks.
