Making a car damaging system with FE Gun Kit But i have trouble damaging the car???

So I'm making a car damaging system. I have the function for turning the car into a pile of scrap once it reaches 0 health, but I have trouble for making the car take damage once a player shoots at it with a gun from FE Gun Kit. Here is my code so far:

while true do
	wait(0.1)
	for i, v in pairs(Car:GetDescendants()) do
		if v:FindFirstChild("Attachment") then
			Health -= 50
		end
	end
end

The bullet part that the gun shoots is actually an Attachment that sticks to where you shot. So I tried making it so when it detects an attachment it lowers the health. However, that does not work. I dont get any errors but it does not lower the health! Please help

(If you want, here is the full code):

local Car = script.Parent.Parent["Humvee (blue)"]
local Health = script.Health
local Script1 = script.Parent["A-Chassis Tune"]
local Script2 = script.Parent.Body.Motors
local Seat = script.Parent.DriveSeat


while true do
	wait(0.5)
	for i, v in pairs(Car:GetDescendants()) do
		if v:FindFirstDescendant("Attachment") then
			Health -= 50
		end
	end
end

while true do
	wait(0.5)
	if Health.Value == 0 then
		for i, v in pairs(Car:GetDescendants()) do
			if v:IsA("Part") or v:IsA("MeshPart") then
				v.Material = Enum.Material.CorrodedMetal
				Script1:Destroy()
				Script2:Destroy()
				if Seat.Occupant then
					Seat.Occupant.Parent.Humanoid.Health = 0
				end
			end
		end
	end
end
