Its a funny error that keeps popping up, here’s the code:

local Players = game:GetService("Players")
local part = script.Parent


local function Touched(Object)
	local Player = game.Players:GetPlayerFromCharacter(Object.Parent)
	
	if not AlreadyTouched and Player then

		
		AlreadyTouched = true 
		print("Good")
		local name = Player.Name
		print(name)
		local Dialog = game.Players:GetPlayerFromCharacter(Object.Parent).PlayerGui.Dialog.Dialog
		local Person = game.Players:GetPlayerFromCharacter(Object.Parent).PlayerGui.Dialog.Person
		local gui = game.Players:GetPlayerFromCharacter(Object.Parent).PlayerGui
	if Object.Parent:FindFirstChild("Humanoid") then

			wait(2)
			game.Players:GetPlayerFromCharacter(Object.Parent).PlayerGui.Dialog.Dialog.Text = "Are you guys ready for the trip?"
			game.Players:GetPlayerFromCharacter(Object.Parent).PlayerGui.Dialog.Person.Text = "dad"
			game.Players:GetPlayerFromCharacter(Object.Parent).PlayerGui.Dialog.Dialog.Visible = true	
			game.Players:GetPlayerFromCharacter(Object.Parent).PlayerGui.Dialog.Person.Visible = true
			
			wait(4)
			Person.Visible = false
			Dialog.Visible = false
			Person.Text = "Mom"
			Dialog.Text = "*slowly dies*"
				Person.Visible = true
				Dialog.Visible = true
				wait(3)
				Person.Visible = false
				Dialog.Visible = false
				wait(2)
			game.Workspace.SoundBlock.TaxiSound:Play()
				wait(2.5)
				Person.Text = "Dad"
				Dialog.Text = "Oh i didnt notice the taxi, lets go!"
				Person.Visible = true
				Dialog.Visible = true
				wait(2)
				Person.Visible = false
				Dialog.Visible = false
				wait(1)
				for i = 1,0,-0.1 do
					gui.BlackScreen.Frame.BackgroundTransparency = i

					wait(0.1)
				end
				
			game.Workspace.Value1.Value = (1)
				
				
				local person =	game.Workspace:FindFirstChild(name)
				person.HumanoidRootPart.CFrame = CFrame.new(Vector3.new(-11.85, 0.511, -105.47))
		end
		for i = 0,1, 0.1 do
			gui.BlackScreen.Frame.BackgroundTransparency = i
			wait(0.1)
		end
	end

You’re using a reference game.Workspace.SoundBlock.TaxiSound:Play()
Make sure it exists first. You can hold a variable:
local soundBlock = workspace:FindFirstChild("SoundBlock")
and check if a child (like TaxiSound) exists as:

if soundBlock:FindFirstChild("TaxiSound") then
    soundBlock.TaxiSound:Play()
end
