Need help with AppleScript!

[lightzebra]

I need a script for AppleScript that allows Safari to load a certain page in different windows every 30 minutes. So far, I've got this:

 

open_safari_window("http://www.apple.com")

on open_safari_window(my_url)
tell application "Safari"
	repeat with i from 1 to 10
		# wake up safari
					activate

		# make a new window
		make new document at end of documents

					# set the URL of this new window
		tell document i
			set URL to my_url
		end tell

					# sleep 1800 seconds (30 minutes)
		delay 1800
	end repeat
end tell
end open_safari_window

 

But it doesn't let me compile it. Can anybody help me out?

It would help if we knew what the exact error message was on the AppleScript.

 

If there is no error, you just Save As...an application.
