Smooth scroll?

Smooth scroll?

Hiii!
I'm making a smooth scroll for an anchor link for in-page movements, and doest'n work  :c 

here's de HTML code:

        <a name="TextoContacto"></a>
   <li><a href="#TextoContacto" class="scroll">Contacto</a></li>
                </ul>

(it works fine)

JS:

$(function() {
 $(".scroll").click(function(event){
 event.preventDefault();
 var offset = $($(this).attr('href')).offset().top;
 $('html, body').animate({scrollTop:offset}, 500);
 });
});
