Looking for validation script

I need a script that validates data such as the Create Account form on this page:

http://www.simplyhired.com/index.php?ds=createaccount&

Does anyone know of such a script?

Thanks in advance.

I don't see a date field within that registration form though? A script that validates date fields (including if the range selected is valid) is: http://www.javascriptkit.com/script/...datedate.shtml
