Is there a way to pre-load an entire GUI?

So I have a GUI that consists of a lot of frames within other frames, and I was having trouble because they stopped working and I was getting the error that the script thought certain frames didn't exist where I said they did, but I fixed some of it by using :WaitForChild(). The problem now, is that the same thing is happening for a lot of the other variables in my scripts (that are within the GUI buttons) and It would take a long time to put the :WaitForChild() in every variable (around 15 variables per script and around 50 scripts) My question is, is it possible to load all of the frames and children of the frames before the scripts run? I think that would solve it but I'm not sure how to do that. Any help is appreciated! Here's an example script

local BUTTON = script.Parent
local nframe = BUTTON.Parent.Parent:WaitForChild("NameFrame")
local name = nframe.Label.Text
local FRAME = BUTTON.Parent.Parent
local NBox1 = FRAME.ColumnFrame2.BoxFrame2
local NBox2 = FRAME.ColumnFrame2.BoxFrame3
local NBox3 = FRAME.ColumnFrame2.BoxFrame4
local NBox4 = FRAME.ColumnFrame2.BoxFrame5

local HBox1 = FRAME.ColumnFrame3.BoxFrame2
local HBox2 = FRAME.ColumnFrame3.BoxFrame3
local HBox3 = FRAME.ColumnFrame3.BoxFrame4
local HBox4 = FRAME.ColumnFrame3.BoxFrame5

local htext1 = HBox1.TextLabel
local ntext1 = NBox1.TextLabel
local htext2 = HBox2.TextLabel
local ntext2 = NBox2.TextLabel
local htext3 = HBox3.TextLabel
local ntext3 = NBox3.TextLabel
local htext4 = HBox4.TextLabel
local ntext4 = NBox4.TextLabel


function getPC()
	local player = game.Players.LocalPlayer
	local char = player.Character

	return player, char
end

function giveTool(name)
	local player, char = getPC()
	local backpack = player.Backpack
	local tools = game.Lighting.Tools

	local made = tools:FindFirstChild(name)

	if made ~= nil then print("toolnotnil")
		made:clone().Parent = backpack
	else print("toolisnil")
	end
end

function giveItem(name)
	local player, char = getPC()
	local pack = player.Pack
	local items = game.Lighting.Items

	local real = items:findFirstChild(name)

	if real ~= nil then
		local new = real:clone()
		new.Parent = pack
	else
	end
end

function delete_items1()
		local player, char = getPC()
	local pack = player.Pack
	local itemname1 = FRAME.RowFrame2.TextLabel.Text
	local item1 = pack:FindFirstChild(itemname1)
	
	item1:remove()
		
end

function delete_items2()
		local player, char = getPC()
	local pack = player.Pack
	local itemname2 = FRAME.RowFrame3.TextLabel.Text
	local item2 = pack:FindFirstChild(itemname2)
	
	item2:remove()
