How do I get this script to clone a GUI and put it in the PlayerGUI?

This question exists solely in my lack of lua knowledge eue.

I'm trying to make a shopkeeper and when you walk near the NPC, it displays a GUI on your screen, simple enough.

function Enter()
	script.NPCDialauge:Clone().Parent = v.Players.PlayerGUI
	script.NPCDialauge:TweenPosition(UDim2.new(0, 500,0, 250), "In", "Sine", 2, true)
end


while true do
	for i, v in pairs (game.Players:GetChildren()) do
		if (v.Character.Torso.Position - script.Parent.Position).magnitude <= 10 then
			Enter()
		end
	end
	wait()
end

How do I get this to clone the GUI and put it in the character who nears the NPC? You can see the obvious error DX I just don't know how to fix it.
