Touched event doesnt work as proper as i want?

Here is my script.

local part1 = nil
script.Parent.RemoteEvent.OnServerEvent:Connect(function(LPx1)
	if LPx1.Character.Humanoid then
		script.Parent.Wedge.Touched:Connect(function(xy)
			if part1 ~= nil then
			print('hi') --it is supposed to print it only once but instead it do it like 50 times
			end
			part1 = xy.Parent
		end)
		wait(.5)
		part1 = nil
	end
end)

How do i make the touch function remote only once not 9999 times? note that that script is undone yet.
