Long script not running before it got splitted?

So i have this line of script:

local player = script.Parent.Parent.Parent.Parent

local playerinfo = player:WaitForChild("Info")
local playerleaderstats = player:WaitForChild("leaderstats")

local playerquest = playerinfo:WaitForChild("Quest")
local playerquestcompleted = playerinfo:WaitForChild("QuestCompleted")

local playercoin = playerleaderstats:WaitForChild("Coin")
local playergems = playerleaderstats:WaitForChild("Gems")
local playerprogress = playerinfo:WaitForChild("QuestProgress")
local playermax = playerinfo:WaitForChild("QuestMax")

local QuestBar = script.Parent.Quest

local QuestName = QuestBar.QuestName.Text
local QuestProgress = QuestBar.Progress.Text
local Reward1 = QuestBar.Reward1.Text
local Reward2 = QuestBar.Reward2.Text



function GiveReward(Coin, Gems)
	playercoin.Value += Coin
	playergems.Value += Gems
	
	playerquestcompleted.Value += 1
end



function GiveQuest(QuestCompleted)
	if QuestCompleted == "MayorA" then
		playerquest = "MayorB"
		
	elseif QuestCompleted == "MayorB" then
		playerquest = "MayorC"
		
	elseif QuestCompleted == "MayorC" then
		playerquest = "MayorD"
		
	elseif QuestCompleted == "MayorD" then
		playerquest = "MayorE"
		
	elseif QuestCompleted == "MayorE" then
		playerquest = "DesertA"
	end
end



while wait(1) do
	if playerquest.Value == "" then
		playerquest.Value = "MayorA"
	end
	
	--Quest
	if playerquest.Value == "MayorA" then
		QuestName = "Find Cat"
		
		if playerprogress == 1 then
			GiveQuest("MayorA")
			GiveReward(250,10)
		end
		
		
	elseif playerquest.Value == "MayorB" then
		QuestName = "Collect 5 Toxic"
		
		
	elseif playerquest.Value == "MayorC" then
		QuestName = "Upgrade Strength to 20"
		
		
	elseif playerquest.Value == "MayorD" then
		QuestName = "Upgrade Backpack to 60"
		
		
	elseif playerquest.Value == "MayorE" then
		QuestName = "Unlock Desert Island"
		
	end
	--End
	
	QuestProgress = playerinfo:WaitForChild("QuestProgress").Value.."/"..playerinfo:WaitForChild("QuestMax").Value
end

But it wont work at all, no output. But when i split em its working!
