How would I go about and make a Module Script for this code?

Improvements

Use WaitForChild() to make sure an instance exists before using it

Use GetService() for the Players Service

Use workspace instead of game.Workspace

Use SetPrimaryPartCFrame to move the player's Character model instead of moving the PrimaryPart only

Use Activated for GuiButtons in order for it to work on all devices and not just computers

Explanation

In the below you can see that I first make a local variable for the module which "requires" the module (Line 3)

Later, when determining the button's Text, I use a function ive defined in the module and send in the button's name as a parameter

In the module script, I make a table dictating the index (which matches my button's name ("Button1") and give this position in the table the value ["Section 7"]

When the function is called, I return this value, which is returned with the module which had previously been "required"

Notice, module scripts only run when you use "require" so it will not run when the server is created like LocalScripts or Server Scripts

Local Script

local player = game:GetService("Players").LocalPlayer
local target = workspace:WaitForChild("Misc"):WaitForChild("TPfloors"):WaitForChild("TPsec7")
local module = require(game:GetService("ReplicatedStorage"):WaitForChild("StringList"))
local button = script.Parent

local db = true
local delay = 2

button.Activated:Connect(function()
	if db == true then
		db = false
		player.Character:SetPrimaryPartCFrame(target.CFrame * CFrame.new(0, 8, 0))
		for i = delay, 1, -1 do
			button.Text = i
			wait(1)
		end
		button.Text = module.StringReturn(button.Name)
		db = true
	end
end)

Module Script

local module = {}

function module.StringReturn(button)
	local stbl = {["Button1"] = "Section 7"}
	return(stbl[button])
end

return(module)

EDIT

Running the same function is similar to changing the button's text, except we'll keep it in the module (it will act like a local function)

Local Script

local player = game:GetService("Players").LocalPlayer
local module = require(game:GetService("ReplicatedStorage"):WaitForChild("StringList"))
local button = script.Parent
local db = true

button.Activated:Connect(function()
	if db == true then
		db = false
		db = module.StringReturn(button, player)
	end
end)

Module Script

local module = {}

local target = workspace:WaitForChild("Misc"):WaitForChild("TPfloors"):WaitForChild("TPsec7")
local delay = 2

function module.StringReturn(button, player)
	local stbl = {["Button1"] = "Section 7"}
	player.Character:SetPrimaryPartCFrame(target.CFrame * CFrame.new(0, 8, 0))
	for i = delay, 1, -1 do
		button.Text = i
		wait(1)
	end
	button.Text = stbl[button.Name]
	return(true)
end

return(module)
