Html_Quick Form rule problem

I having problem with the following rules. // Define filters and validation rules $ClientLoginForm_obj->addRule('cust_email', 'Email is incorrect', 'email','',''); $ClientLoginForm_obj->addRule('cust_email', 'Email is required', 'required','',''); $ClientLoginForm_obj->addRule('cust_passwd','Password is required', 'required','',''); $ClientLoginForm_obj->addRule('cust_passwd','Password is small', 'minlength','3',''); If i enter a valid email but no password, it some how goes through. It should now allow at all to go forward if any of the fields are blank. Thanks Atif
