The Zarm Script is goint to randomPlayer how do i use this?

local randomPlayer = game.Players:GetPlayers()[math.random(1,#game.Players:GetPlayers())]

local owner = game.Lighting.Infected.Name

if randomPlayer.Parent == nil then return end

local h = randomPlayer.Parent:findFirstChild("Humanoid")

if h == nil then return end

if game.Players:findFirstChild(randomPlayer.Parent.Name) == nil then return end


if randomPlayer.Parent.Name == owner then return end
						
if h.Parent:findFirstChild("zarm")~=nil then return end

local larm=h.Parent:findFirstChild("Left Arm")
local rarm=h.Parent:findFirstChild("Right Arm")
						
if larm~=nil then larm:remove() end
if rarm~=nil then rarm:remove() end

local zee=game.Lighting.Infected:findFirstChild("zarm")

if zee == nil then return end

local zlarm=zee:clone()
local zrarm=zee:clone()

local rot=CFrame.new(0, 0, 0, 0, 0, 1, 0, 1, 0, -1, 0, 0)
zlarm.CFrame=h.Parent.Torso.CFrame * CFrame.new(Vector3.new(-1.5,0.5,-0.5)) * rot
zrarm.CFrame=h.Parent.Torso.CFrame * CFrame.new(Vector3.new(1.5,0.5,-0.5)) * rot
zlarm.Parent=h.Parent
zrarm.Parent=h.Parent
zlarm:makeJoints()
zrarm:makeJoints()
zlarm.Anchored=false
zrarm.Anchored=false
wait(0.1)
h.Parent.Head.Color=zee.Color

local newtag = game.Lighting.Infected:clone()
newtag.Parent = h.Parent
