Is it possible to apply a local function to an array?

This part of the script is supposed to make the previously created 5 parts heal what they touch, but Output returns: Attempt to index field 'Touched'(a nil value)

		wait()
		local h = game.Workspace
		local durt = {h.durt1,h.durt2,h.durt3,h.durt4,h.durt5}
		local function onTouch(hit)
			if hit.Parent.FindFirstChild("Humanoid") then
			local hp = hit.Parent.Character.Humanoid.Health
			hp = hp+hp+durt.Size*5
		end
			end
		durt.Touched:connect(onTouch)
