Why wont the int value decrease?

Following my last question, thats been answered, I've joined 2 scripts so when the cannon ball hits the boat, it explodes, and takes 20 away from the int value. Now it had been working for a while, but when i turned, on line 47, math.random(1,3), into true, it has stopped decreasing. I'm pretty sure its a small error, but nothings coming out in the console. So can you guys please help identifying the problem?

ball = script.Parent
damage = 50
local debounce = true
function onTouched(hit)
	local RESET_SECONDS = 5
	local isTouched = false 


	ball.Touched:Connect(function(part)
		if isTouched then return end

		local car = ball:FindFirstAncestor("car")
		local value = if car then car:FindFirstChild("Int", true) else nil

		if not value then return end

		isTouched = true
		value.Value -= 20

		wait(RESET_SECONDS)
		isTouched = false
	end)


	local humanoid = hit.Parent:findFirstChild("Humanoid")
	if humanoid~=nil then
		tagHumanoid(humanoid)
		humanoid.Health = humanoid.Health - damage
		if debounce then
			debounce = false
			if humanoid.Health == 0 or humanoid.Health < 0 then
				local z = game.Players:FindFirstChild(game.ReplicatedStorage.asd.Value)
				z.leaderstats.Kills.Value += 1
				wait(2)
				debounce = true
			end
		end

		untagHumanoid(humanoid)
	else
		damage = damage / 2
		if damage < 2 then
			ball.Parent = nil
		end
	end

	if true then
		local explosion = Instance.new("Explosion")
		explosion.BlastRadius = 9
		explosion.BlastPressure = 1000000 -- these are really wussy units
		explosion.Position = script.Parent.Position
		explosion.Parent = game.Workspace
		connection:disconnect()
		ball.Parent = nil
	end

end

function tagHumanoid(humanoid)
	-- todo: make tag expire
	local tag = ball:findFirstChild("creator")
	if tag ~= nil then
		local new_tag = tag:clone()
		new_tag.Parent = humanoid
	end
end


function untagHumanoid(humanoid)
	if humanoid ~= nil then
		local tag = humanoid:findFirstChild("creator")
		if tag ~= nil then
			tag.Parent = nil
		end
	end
end

connection = ball.Touched:connect(onTouched)

r = game:service("RunService")
t, s = r.Stepped:wait()
d = t + 5.0 - s
while t < d do
	t = r.Stepped:wait()
end

ball.Parent = nil
