Making players spectate on death, then respawn next round

[striker1013]

I've decided to make a gamemode for learning purposes and to practice GLUA, I'm have issues setting up spectating and team switching on death.
Basically I'm trying to make a dead player change to a different team then spectate, then when the round ends change them back to the "alive" team and let them spawn again. Also I don't want players who join in the middle of the round so I want them to join in on the spectator team so that people can't abuse it.

init.lua

local fol = GM.FolderName.."/gamemode/modules/"
local files, folders = file.Find(fol .. "*", "LUA")



for k,v in pairs(files) do
	include(fol .. v)
end


for _, folder in SortedPairs(folders, true) do
	if folder == "." or folder == ".." then continue end

	for _, File in SortedPairs(file.Find(fol .. folder .."/sh_*.lua", "LUA"), true) do
		AddCSLuaFile(fol..folder .. "/" ..File)
		include(fol.. folder .. "/" ..File)
	end
end
for _, folder in SortedPairs(folders, true) do
	if folder == "." or folder == ".." then continue end

	for _, File in SortedPairs(file.Find(fol .. folder .."/sv_*.lua", "LUA"), true) do
		include(fol.. folder .. "/" ..File)
	end
end

for _, folder in SortedPairs(folders, true) do
	if folder == "." or folder == ".." then continue end

	for _, File in SortedPairs(file.Find(fol .. folder .."/cl_*.lua", "LUA"), true) do
		AddCSLuaFile(fol.. folder .. "/" ..File)
	end
end

local TEAM_SPEC, TEAM_NEUTRAL = 1, 2
local alivePlayers = 0

round = {}
round.Break	= 10
round.Time	= 20
round.TimeLeft = -1
round.Breaking = false

function GM:PlayerSpawn( ply )
	
	--if !round.Breaking then

I don't understand this. I have mixed this code around at least 10 times trying to get players spectating on death and respawn when the round ends. The code is probably kind of messed up because of the many times I've tried new things to get it working. If anyone has any suggestions please feel free to share.

Thank you all so much for the help you provide and the time you take to aid us that have less knowledge.

I've tried more things lol.

Very strange. None of this is working.
