Help With 'Return'? (ANSWERED)

So I have a script inside of a part called 'Glass'

Whenever something touches it with a Parent named 'Zombie' it takes away one from a value called 'Health' in the Part.

The script works fine, if the zombie touches it first. But if the player touches it first, then the zombie won't make any change to it.

I think I know how to fix this, but I'm not sure. I think I have to use 'else return' somewhere, but everywhere i tried to put it it didn't work.

This is the script inside the glass part:

local db = 0
local health = script.Parent:WaitForChild("Health")

function onTouched(hit)
	local player = game.Players:GetPlayerFromCharacter(hit.Parent)
	local human = hit.Parent:findFirstChild("Humanoid")
	if db == 0 then
		db = 1
		if hit.Parent.Name == "Zombie" then
		health.Value = health.Value - 1
		print("ow")
		print(health.Value)
		wait(math.random(1,3))
		db = 0
		
		end
		end
	end
	

script.Parent.Touched:connect(onTouched)

local db = 0
local health = script.Parent.Health

script.Parent.Touched:connect(function(h)	
	if db == 0 then
		if h.Parent.Name == "Zombie" then
			db = 1
			health.Value = health.Value - 1
			print("OW!")
			print(health.Value)
			wait(math.random(1, 3))
			db = 0
		end
	end
end)

You can add back in your variables, but this functions regardless of what touches the block first. (Tested by making a clone of myself named 'zombie' touch the brick after I had.
