googlemapselector.js not working

I'm trying to use the google map program on my website but I cannot download googlemapselector.js
I keep getting an error message

Please include a link to the DD script in the future, in this case, http://www.dynamicdrive.com/dynamici...apselector.htm

What do you mean you can't download the file, that it doesn't exist? The following reference is valid for me: http://www.dynamicdrive.com/dynamici...mapselector.js

the downloaded file is only 3kb. When I click on it, I get a Microsoft runtime jscript error line 20 char 3 object expected code 800A138F
