Command Not Working When the Message is Chatted?

Me and my friends make questionable things, and I need to make a flickering light that only flickers back on when you message a certain command. The flickering is fine, it's just the command isn't working. Please help, I don't understand what is wrong. Here is the full script.

local bulb = script.Parent
local light = bulb.SpotLight
local command = "*hits light*"
local hittimes = math.random(25,50)
print("Max times to hit the light:"..hittimes..".")
local onoff = 1
local counttimes = 0

light.Brightness = 12.28
bulb.Color = Color3.new(0.972549, 0.85098, 0.427451)
--establishing prior bulb

local function flickoff()
	local waittime = math.random(60,120)
	local flickers = math.random(1,4)
	print(waittime,flickers)
	--wait waittime
	wait(waittime)
	--flicker
	for i=1,flickers,1 do
		light.Brightness = 0
		bulb.Color = Color3.new(0,0,0)
		wait(.1)
		light.Brightness = 12.28
		bulb.Color = Color3.new(0.972549, 0.85098, 0.427451)
		wait(.1)
	end
	light.Brightness = 0
	bulb.Color = Color3.new(0,0,0)
end

local function flickon()
	local flickers = math.random(1,4)
	print(flickers)

	--flicker
	for i=1,flickers,1 do
		
		light.Brightness = 12.28
		bulb.Color = Color3.new(0.972549, 0.85098, 0.427451)
		wait(.1)
		light.Brightness = 0
		bulb.Color = Color3.new(0,0,0)
		wait(.1)
	end

	light.Brightness = 12.28
	bulb.Color = Color3.new(0.972549, 0.85098, 0.427451)
end

local function bulbgo()
	if counttimes<=hittimes then
		if onoff == 1 then
			flickoff()
			onoff=onoff-1
		else
			light.Brightness = 0
			bulb.Color = Color3.new(0,0,0)
		end
	end
end

bulbgo()

game:GetService("Players").PlayerAdded:connect(function(plr)
	plr.Chatted:connect(function(msg)
		--print(plr.Name.." said "..msg..".")
		local asd = string.find(msg,command)
		if asd == 1 then
			flickon()
			onoff=onoff+1
			bulbgo()
		else
		end
	end)
