Anyone help with this script?

So I took a copy off of a game and I decided to revamp it. But I can NOT get the random audio working. So, here's the script. I only want the script to play a random audio as soon as zombies/humans win the game. But I can't get it working.

``

p = game.Players:getChildren()
local zombie = math.random(1, #p)
for i = 1, #p do
if (i == zombie) then
p[i].TeamColor = BrickColor.new("Sand green")
else
p[i].TeamColor = BrickColor.new("Bright red")
end
end

m.Text = "If all survivors die, the zombies win!"
wait(1)
for i = 1, #p do
if p[i].Character ~= nil then
	if p[i].TeamColor == BrickColor.new("Bright red") then
		local spawn = math.random(1, #humSpawns)
		p[i].Character.Torso.CFrame = CFrame.new(humSpawns[spawn].Position + Vector3.new(0, 6, 0))
	elseif p[i].TeamColor == BrickColor.new("Sand green") then
		zombify(p[i])
		local spawn = math.random(1, #zombSpawns)
		p[i].Character.Torso.CFrame = CFrame.new(zombSpawns[spawn].Position + Vector3.new(0, 6, 0))
	end
end
end
m.Text = "Choose your weapons and begin!"
game.Workspace.Rawr:play()
game.workspace.Music:play()
wait(3)
m:remove()

script.Running.Value = 1
local time = roundtime  --Time, in seconds.

while script.Running.Value == 1 do
	if math.fmod(time, 60) < 10 then
	scorebar.Text = "Time Remaining:  " .. math.floor(time/50) .. ":0" .. math.fmod(time, 60)
	else
	scorebar.Text = "Time Remaining:  " .. math.floor(time/60) .. ":" .. math.fmod(time, 60)
	end
	wait(1)
	time = time - 1
	if time == 0 then


		print("game ovarrrrrrr")
		script.Running.Value = 0

	end
