Owner Only Seat script for UserId?

So I've gotten a free script that only works with usernames however, I'm trying to change it to detect the userId. Please help, thank you! local seat = script.Parent

seat.ChildAdded:connect(function( newChild )	
	if newChild:IsA("Weld") then
		if newChild.Part1.Name == "HumanoidRootPart" then
			local player = game.Players:GetPlayerFromCharacter(newChild.Part1.Parent)
			if (player) then
				if player.UserId == script.Parent.Parent.Name then
					--code here or leave blank
				else
					newChild.Part1.Parent.Humanoid.Health = 0 -- kills player
				end
			end
		end
	end
end)

The folder the seat is in is named after the player's userid, there's two parents.

Ok, here it is.

local seat = script.Parent -- gets seat
game.Players.PlayerAdded:connect(function(p) -- checks if player has added
	local owner = Instance.new("StringValue",p) -- adds a string value to the player
	owner.Name = "OwnerValue" -- names the value OwnerValue
	owner.Value = "nil" -- this will be changed to either true or false
	if (p.UserId == game.CreatorId) then -- checks if player user id is the creator id
		owner.Value == "true" -- sets owner value to true
	else
		owner.Value == "false" -- sets owner value to false
	end
	p.CharacterAdded:connect(function(char) -- checks if character is added
		wait() -- about the quickest tick you can get, any faster will make you lag
		local h = char.Humanoid -- gets the humanoid
		h.Changed:connect(function() -- checks if humanoid has changed any value
			if (h.SeatPart == seat) and (owner.Value=="false") then -- checks if on seat and not owner
				char:BreakJoints() -- kills the player
			end
		end)
	end)
end)

You could make a religion out of this.

At code here or leave blank, leave it blank. In the future, try not to use free scripts. But great job trying to edit it. ;)
