G'Day Lauren,
In this instance I think I'll back-pedal and go with Larry's original
assessment :-)

That's because the version you are seeing has already been parsed by the
server and the bits between <% and %> have been transformed into HTML

Because you don't get the whole code, only the results. Let's see if I can
find a simple example:
1. Imagine a page that grabbed the current day and wrote "Today is Friday"
(well it is here at any rate :-)
2. You have saved this HTML source and publish it on a web site
3. Someone visits the site on Wednesday. On your site it would say "Today
is Friday" because that's what the HTML says. On the original site it
would again grab the correct day and state "Today is Wednesday".
This is the problem in it's simplest case - it can get MUCH
worse!! Depending upon circumstances, the same ASP page could display
either a login script, a form requesting input, or a results page from the
form - all in the one script!
With FTP access, you can access the original files before they are
processed by the web server.
