My minigame script is breaking?

I used this script for my minigames -

AutomaticTimer = false 
CashValue = "Points" 
WinnerCash = 20 
SurvivorCash = 12
FinishCash = 5 
Time = 60 
Intermission = 10 

hint = Instance.new('Hint',Workspace)

while true do
	WinnerName = nil
	value = Intermission
	while value > 0 do
		hint.Text = "Intermission ("..value..")"
		value = value-1
		wait(1)
	end
hint.Text = "A minigame will be selected..."
wait(3)
m = game.Lighting.Minigames:GetChildren()
n = math.random(1,#m)
minigame = m[n]
hint.Text = "The minigame is '"..minigame.Name.."'!"
map = minigame:clone()
map.Parent = Workspace
wait(3)
hint.Text = map.Description.Value
plrs = game.Players:GetChildren()
	for i = 1, #plrs do
		if plrs[i].PlayerGui.PlayGui.Button.Playing.Value == true then
			plrs[i].Character:MoveTo(map.Spawn.Position)
		end
	end
	if map.GameType.Value == "Race" or map.GameType.Value == "Obby" then
		value = 5
		while value > 0 do
			hint.Text = "The round will begin in "..value..""
			value = value-1
			wait(1)
		end
		for i = 0.05, 1, 0.05 do
			map.Wall.Transparency = i
			wait()
		end
		map.Wall.CanCollide = false
		WinnerFinished = false
		map.Finish.Touched:connect(function(hit)
			if hit.Parent:findFirstChild("Humanoid") ~= nil then
				local plr = game.Players:findFirstChild(hit.Parent.Name)
				local cash = plr.leaderstats:findFirstChild(CashValue)
				if not WinnerFinished then
					cash.Value = cash.Value+WinnerCash
					WinnerName = plr.Name
					WinnerFinished = true
				else cash.Value = cash.Value+FinishCash
				end
				hit.Parent:MoveTo(Workspace.GameSpawn.Position)
				local t = hit.Parent:findFirstChild('Survived')
				if t ~= nil then
					t:remove()
				end
				local h = hit.Parent:findFirstChild('SurvivalCheck')
				if h ~= nil then
					h:remove()
				end
			end
		end)
	end
	plrs = game.Players:GetChildren()
	for i = 1, #plrs do
		if plrs[i].PlayerGui.PlayGui.Button.Playing.Value == true then
			v = Instance.new('BoolValue')
			v.Parent = plrs[i].Character
			v.Name = "Survived"
			v.Value = true
			s = script.SurvivalCheck:clone()
			s.Parent = plrs[i].Character
			s.Disabled = false
		end
	end
	if map.GameType.Value == "Survival" or map.GameType.Value == "Custom" then
		value = 5
		while value > 0 do
			hint.Text = "The round will begin in "..value..""
			value = value-1
			wait(1)
		end
		plrs = game.Players:GetChildren()
		for i = 1, #plrs do
			map.DisasterScript.Disabled = false
		end
	end
	if not AutomaticTimer then
		Time = minigame.Time.Value
	end	
	value = Time
	while value > 0 do
		hint.Text = "Time left: "..value..""
		value = value-1
		wait(1)
	end
	hint.Text = "Round over!"
	if map.GameType.Value == "Race" or map.GameType.Value == "Obby" then
		if WinnerName ~= nil then
			hint.Text = "The winner was: "..WinnerName.."!"
		else
			hint.Text = "There was no winner this round!"
		end
	elseif map.GameType.Value == "Survival" or map.GameType.Value == "Custom" then
		plrs = game.Players:GetChildren()
		for i = 1, #plrs do
			local s = plrs[i].Character:findFirstChild('SurvivalCheck')
			if s ~= nil then
				s:remove()
			end
			local t = plrs[i].Character:findFirstChild('Survived')
			if t ~= nil then
				if t.Value == true then
					plrs[i].leaderstats.Points.Value = plrs[i].leaderstats.Points.Value+SurvivorCash
				end
			end
		end
	end
	if map.GameType == "Custom" then
		plrs[i].Character:BreakJoints()
	end
	map:remove()
	wait(1)
	for i = 1, #plrs do
		local t = plrs[i].Character:findFirstChild('Survived')
		if t ~= nil then
			if t.Value == true then
				plrs[i].Character:MoveTo(Workspace.GameSpawn.Position or Workspace.GameSpawn2.Position)
			end
		end
	end
	wait(3)
end

I picked up an error on line 77 about SurvivalCheck. The problem is, whenever it teleports players to the map, the whole script breaks. In output, I get - SurvivalCheck is not a valid member of Script

Here's the SurvivalCheck script -

script.Parent.Humanoid.Died:connect(function()
	script.Parent.Survived.Value = false
end)

Any help?

You've written it saying that the SurvivalCheck script is inside that main script. is this true, where is the Survival Check script?

The way you have it set up is that the SurvivalCheck script's parent is the main script.
