Why??
How about 63 errors and 25 warnings within your Html and they have nothing to do with the script you are trying to get working.
http://meteocaianello.altervista.org/wxnewpage.phpYou can not keep producing these pages and then asking people to help unless you stop and help yourself. Click on that link 'verify XHTML' in your footer from that page and start working on those problems.
Then when you want to add a new script you at least have one page that works correctly.
Sorry if I sound mean but these errors and such should not be ignored
