Unknown global 'player' in a local script?

I'm trying to give a badge every time this function fires. I have one script and one localscript. It does not give me any indication of anything happening. I've been trying to fix this for a week now and I've practically given up.

Here is the script:

local Knock = script.Parent.Knock
local a = script.Parent
local knockbadgeEvent = game.ServerStorage.knockbadge

while true do
    wait(math.random(5,6))
    knockbadgeEvent:FireAllClients()
    Knock:Play()
    a.Material = "SmoothPlastic"
    script.Parent.SurfaceLight.Brightness = 0
    wait(.05)
    a.Material = "Neon"
    script.Parent.SurfaceLight.Brightness = 0.5
    wait(.05)
    a.Material = "SmoothPlastic"
    script.Parent.SurfaceLight.Brightness = 0
    wait(1.9)
    a.Material = "Neon"
    script.Parent.SurfaceLight.Brightness = 0.3
    wait(.1)
    script.Parent.SurfaceLight.Brightness = 0.6
    wait(.1)
    script.Parent.SurfaceLight.Brightness = 1
    wait(.4)
    a.Material = "SmoothPlastic"
    wait(.05)
    a.Material = "Neon"
    script.Parent.SurfaceLight.Brightness = 0.5
    wait(.05)
    a.Material = "SmoothPlastic"
    script.Parent.SurfaceLight.Brightness = 0
    wait(1.5)
    a.Material = "Neon"
    script.Parent.SurfaceLight.Brightness = 0.3
    wait(.1)
    script.Parent.SurfaceLight.Brightness = 0.6
    wait(.1)
    script.Parent.SurfaceLight.Brightness = 1
    wait(.5)
    a.Material = "SmoothPlastic"
    wait(.05)
    a.Material = "Neon"
    script.Parent.SurfaceLight.Brightness = 0.5
    wait(.05)
    a.Material = "SmoothPlastic"
    script.Parent.SurfaceLight.Brightness = 0
    wait(1.4)
    a.Material = "Neon"
    script.Parent.SurfaceLight.Brightness = 0.3
    wait(.1)
    script.Parent.SurfaceLight.Brightness = 0.6
    wait(.1)
    script.Parent.SurfaceLight.Brightness = 1
end

And here is the localscript:

local badgeID = 2124476391
local bs = game:GetService("BadgeService")

local function onknockbadgeFired()
    bs:AwardBadge(player.UserId, badgeID)
end

I've tried defining player as game.Players.LocalPlayer but that doesn't work either!
