First, I would recommend placing the javascript at the end of the BODY section for both performance reasons (see http://developer.yahoo.com/performance/rules.html#js_bottom) and because the call to addValidationForField is going to be looking for the element in the HTML so if it hasn't loaded yet, it won't find it.

Second, I don't think I said it in the blog post, but I'm pretty sure for formValidation.js depends on prototype.js so be sure to include that too. I recommend using Google's hosted copy at http://ajax.googleapis.com/ajax/libs/prototype/1.6.0.2/prototype.js to both save bandwidth on your site, but also to take advantage of it being pre-cached in your browser from someone else's web page.

Hi Steven, this validation method is amazing.. but i cant figure out how to use it..

called the formValidation.js file on my HEAD section...

add this:
vf.addValidationForField("email", "email", "email");

added the fieldWithErrors class to my CSS file...

on my form i have an input field with the id 'email'..

AM I MISSING SOMETHING?
SHOULD THIS WORK LIKE THIS???

sorry for bother..
