You would need to code it into a functioning web page. I would recommend hiring an XHTML/CSS coder, but they are not cheap, unless you know how to do it yourself. Then you put it on the server and it's all up and running.
i think slicing a peace of templates is not necessary!! it won't doing any change with your site, have you try to installs any of the scrip that are available in your fantastico? may be this could help you! if you haven't done installing any scrip then your page won't be visible on the net.
