Minigame script breaks when I put in the script for the second map, any ideas?

So I'm really new to scripting and am trying to make a simple minigame to kickstart me. I have 2 maps, and when I keep out the script for the 2nd map it works fine. However, when I put in the script for the second map, the entire script breaks and I don't know what the problem is. Hopefully this isn't too long for help.

m = Instance.new('Message', workspace)
h = Instance.new('Hint', workspace)
local sword = game.Lighting.ClassicSword:Clone()
num = math.random(1,2)
map = game.Lighting.SF:Clone()
map2 = game.Lighting.Obby:Clone()
players = game.Players:GetChildren()
while true do
    wait(1)
    for i = 5, 1, -1 do
        h.Text = "Choosing map in: "..i
        wait(1)
    end
    h:Remove()


    if num == 1 then -- if the first map is picked
        h = Instance.new('Hint', workspace)
        m.Text = "Map Number "..num.." Has Been Chosen!"
        wait(3)
        m.Text = "Sword Fight, Created by EternallySpeedy"
        wait(3)
        m.Text = "Be the last one alive!"
        m:Remove()
        wait(3)
        h.Text = "Loading Map..."
        wait(5)
        map.Parent = game.Workspace -- loading the map
        map.Name = "Map"
        map:MakeJoints()
        h.Text = "Teleporting Players..."
        wait(3)
        h:Remove()
        target = Vector3.new(48.7, 0.5, 32.455) -- teleporting the players
        for i, v in pairs(game.Players:GetChildren()) do
        v.Character.Torso.CFrame = CFrame.new(target + Vector3.new(0, i * 5, 0))
        m = Instance.new('Message', workspace)
        h = Instance.new('Hint', workspace)
        m.Text = "3"

        wait(1)
        m.Text = "Begin!"
        wait(1)
        m:Remove()
        sword:Clone().Parent = game.Players.LocalPlayer.Backpack
        end
        for i = 60, 1, -1 do
            h.Text = "Round ends in: "..i -- countdown until the round is over
            wait(1)
            end
        h.Text = "The round is over."
        wait(1)
        map:Remove()
        wait(5)
        end
    for i = 15, 1, -1 do -- countdown until the loop restarts
        h.Text = "Intermission: "..i
        wait(1)
        end
        m:Remove()
