Why my script to appear GUI when you click block doesn't works?

Hello! I'm trying to make GUI appear when I touch block. I did this script below but it doesn't works, also I don't have any errors, any ideas what should I change? (script is in local script)

local Player = game.Players.LocalPlayer

local function change(hit)
	if hit.Parent and hit.Parent:FindFirstChild("Humanoid") then
		
		Player.PlayerGui.UniformGui.Frame.Visible=true
		
	end
end


script.Parent.Touched:Connect(change)

LocalScripts will not run in the Workspace if they are not parented to a player's Character. Think of it this way:

A local script relies on a client to function properly. Without a client there is nothing "local" to refer to, because only the server exists, and the server is not "local". If a local script is parented to StarterGui, the script gets cloned to PlayerGui, and since PlayerGui is associated with a player, the script is able to function. However, if you put it somewhere that it will never obtain a client from, it will cease to function.

You can do this in a local script not parented to the Workspace unless under the Character by referring to the part to be touched as a separate Instance not initially associated with the local script. It will then be able to obtain the script signal and allow it to fire.
