Gui Holo help?

local LName = script.Parent["MapName"].Value
local Map = game.Workspace["Map"]
local Glass = game.Workspace["Glass"]:GetChildren()
local Spawn = game.Workspace.Glass["Spawn"]
local Door1 = game.Workspace["Door1"]
local Door2 = game.Workspace["Door2"]
script.Parent.Name = LName

script.Parent.MouseButton1Down:connect(function()
    script.Parent.Parent.Active = false
    script.Parent.Parent.Visible = false
    local test = Map:GetChildren()
    if #test >= 1 then
        game.Workspace["Map"]:ClearAllChildren()
    end
    local Players = game.Players:GetChildren()
    for i = 1, #Players do
        local x = math.random(-10, 10)
        local z = math.random(-10, 10)
        Players[i].Character:MoveTo(Vector3.new(Spawn.Position.x + x, Spawn.Position.y, Spawn.Position.z + z))
        wait()
    end
    for b = 1, #Glass do
        Glass[b].Transparency = 0.5
    end
    Door1.Transparency = 0
    Door2.Transparency = 0
    wait(1)
    Map:ClearAllChildren()
    local Maps = game.Lighting["Maps"]
    local Maps = game.Lighting["Maps"]
    local aav = Maps[LName]
    local Clone = aav:Clone()
    Clone.Parent = Map
    for b = 1, #Glass do
        Glass[b].Transparency = 0.5
    end
    local M = Instance.new("Message")
    M.Parent = game.Workspace
    M.Text = "Map Loaded."
    wait(5)
    M:Destroy()
end)

This is the code that runs in my specialized holo. I have rewritten it so many times trying to make it generalized but the code seems to tease me and not work D:

This code needs to be generalized so that all is required is a map change name. Keep in mind all maps will be in lighting. If you have any ideas please message me via here or in Roblox. Thanks for reading and double thanks if you help me. Can anyone help me?
