My intro wont work!

HERE IS MY SCRIPT!

 wait (2)
 for i = 1, 10 do
	trans = 1/10
	trans = 1 - trans
	script.Parent.BG.BackgroundTransparency = trans
	wait (.1)
 end

 script.Parent.BG.Text1.Text = "Welcome to the town of Rosedale!"
 wait (3)
 script.Parent.BG.Text2.Text = "I am your real estate agent, Amy"
 wait (3)
 script.Parent.BG.Text3.Text = "I will also show you around town!"
 wait (3)
 script.Parent.BG.Text4.Text = "chat ok to begin playing!"
 script.Parent.Parent.Parent.Chatted:connect(function(msg)
	if script ~= nil then
	message = msg:lower()
	if message == "ok" then
	script.Parent.BG.Text1.Text = "Here is where all the stores are,"
	wait (5)
	script.Parent.BG.Text2.Text = "Now here, is the park."
	wait (5)
	script.Parent.BG.Text3.Text = "And here, is the school."
	wait (5)
	script.Parent.BG.Text4.Text = "And most important, here are all the houses."
	wait (.2)
	for i = 1, 10 do
	trans = 1/10
	script.Parent.BG.BackgroundTransparency = trans
	wait (.1)
	end
	x = Instance.new("IntValue" , script.Parent.Parent.Parent)
	x.Name = "WentThroughCutscene"
	script.Parent:remove()
	end
   end
   end)

Once you chat ok, more text is supposed to pop up and its supposed to turn into a cutscene, But it wont work.

This is the script you asked for on ROBLOX from "The Football Coach"....It'll take lots of editing to match your game set but have fun!
