What would i have to write to do to make a part open a shop?

I created a ring where the player is supposed to step on to open the shop my script however wont work:

local Buy = script.Parent

Buy.Touched:Connect(function(HIT)
	local H = HIT.Parent:FindFirstChild("Humanoid")
	if H then
		local Player = game.Players:GetPlayerFromCharacter(HIT.Parent)
		Player.PlayerGui.Shop.Enabled = true
		
	end
end)

So can anyone tell me what i should write/do instead?
