When I validate my site counsellinginfo.blogspot.com with validator.w3.org , it shows errors, am not able to fix them, can anyone help me with this. Thanks
It depends on what the errors are. If you want someone to fix it for you, you'll probably have to pay - there are a lot of errors on the page, even beyond what validation will show.
Fix the errors ONE AT A TIME FROM THE TOP DOWN. One error can cause multiple "implied" errors. When you fix an error, all "implied" errors caused by that error disappear. The first error on your page can be fixed by encoding the ampersand. Go read the link in the error message, then fix the ampersands in your code. That will probably remove most of your errors.
You have so many errors just on the main page. I would agree with creativewebmaster if you don't know how to do it yourself.
