My theme does not validate anymore?

After installing WP 2.2 I found out that my HTML would not validate any more. It was generating annoying errors about using ID=”links” more than once on a web page. All of these errors were occurring courtesy of the built-in links widget. It took me some time but I finally found the problem. I noticed that I was not getting the same type of error when I used a different theme. That led me to look at the functions.php in both themes. In the theme that worked correctly the links widget was redefined. In the Andreas09 theme the links widget was not changed. So I copied over the code that was working properly and integrated it into the Andreas09 theme. After a suitable amount of praying and crossing of my fingers and toes, I switched over to the modified version of the functions.php and refreshed the screen. Lo and behold, it worked!
