User Authentication

Looking for someone expert in ASP,to modify and implement new functions to the attached script,I have found on internet. It needs to allow the acces to web page to users that are registered. I need the following functions : 1. Add the following fields to DB and form : Country , State, City Ecah of them is a combo containing Country,States and City world [login to view URL] User chooses the Country,then against this the State combo is Updated,The user chooses the State,the City Combo is updated for that State. 2. Add a chaptcha to avoid non-human registrations. 3. The module UpdateProfile ( [login to view URL]) doesn't store the user changes. Please correct it. 4. Give a Web2.0 look style to forms (see for example [login to view URL])
