Unfortunately there's nothing available server side on NTL's hosting for CGI scripting et al so youre stuck with Client Side stuff like Java/Javascript unless you go buy some dedicated hosting from somewhere like
www.hostforweb.com where u can get a decent hosting package from as little as £2/month which im sure you find in spare change. Im sure someone will come along and promote the offer with the host of this site has for forum members.
