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)
