Add Tabbed info Window to Google Map Api Mashup

I have put together a Google mashup that is working fine. As I am not a programmer and just tinkered and pasted code together from various different online tutorials and docs on Google Maps Api. I am now stuck. All I am looking for is for someone to please add the missing variables and functions in the right places etc.. for tabbed info windows. I have the html file and javascript in place as well as the xml file that the locations are being pulled from. Basicly I want everything to work just as is now with the addition of tabbed infowindows. Please see site: [login to view URL] Html File: [login to view URL] XML File: [login to view URL] In the near future I would be interested in going from using an xml data source to a MySql db. Thanks Mike
