Damage script works only once?

I have the part here: https://gyazo.com/afd73a7fec4f7d097e99a3dcb95d2076 And it does work, but the problem is only once, when the ai walked into the other one it damaged him but only that time then it just did nothing. Example: https://gyazo.com/6789f6f4c1fc9d7a6552cd3add2f3338 (It did damage it, it just healed before I could get it in the gif) How do I fix it??

script.Parent.Touched:connect(function(part)
	local humanoid1 = part.Parent:FindFirstChild("Humanoid")
	local humanoid2 = part.Parent.Parent:FindFirstChild("Humanoid")
	if humanoid1 then
		humanoid1:TakeDamage(script.Parent.Damage.Value)
	end
	if humanoid2 then
		humanoid2:TakeDamage(script.Parent.Damage.Value)
	end
end)

Try this;

script.Parent.Touched:connect(function(hit)
	
	if hit.Parent:FindFirstChild("Humanoid") then
		
		hit.Parent.Humanoid:TakeDamage(script.Parent.Damage.Value)
		
	elseif hit.Parent.Parent:FindFirstChild("Humanoid") then
		
		hit.Parent.Parent.Humanoid:TakeDamage(script.Parent.Damage.Value)
		
	end
	
end)

Might work.

Put a part in ReplicatedStorage and put this script in it :

script.Parent.Touched:connect(function(part)
    local humanoid1 = part.Parent:FindFirstChild("Humanoid")
    local humanoid2 = part.Parent.Parent:FindFirstChild("Humanoid")
    if humanoid1 then
        humanoid1:TakeDamage(script.Parent.Damage.Value)
    end
    if humanoid2 then
        humanoid2:TakeDamage(script.Parent.Damage.Value)
    end
game.ReplicatedStorage.PARTNAME:Clone().Parent = game.workspace
end)

And put another part with this script in workspace.

I hope it helped !
