I want to make a UIScale Button. but when i test to click on the button it says this

 UIScale is not a valid member of ScreenGui

can someonehelp me ??

script.Parent.MouseButton1Down:connect(function(click)
	game.Players.LocalPlayer.PlayerGui.Play.UIScale = 1.5
	game.StarterGui.Play.UIScale = 1.5
end)

Hi, it looks like you meant the Size? ScreenGuis don't a scale property, as they encompass the entire screen of the client already. What you can do is adjust the size of the frames inside of your screen.
