Validation Error

Hi Guys,

I have a website with allows new users to join the site. the registration form has username and email validations. The problem is with the validation… for some reasons its throwing an error. Appreciate any help.
attaching the required files.

Link: is my site—> Community—> click on join to see the registration form.

Thanks in advance.

When the page loads, this error appears:

which refers to this:

<div id="bannerAd"><script type="text/javascript">
htmlAdWH("93166237", "728", "90");

Obviously the function htmlAdWH is not running because it isn’t defined.

Get Firebug
