That means that inside a single field in the FieldStorage object, you
want a list of all the items where a checkbox was selected.

Since you're probably varying the filename and fullname for each
generated checkbox, this won't satisfy that criteria I gave above -
each checkbox in this case will have a different "name" attribute, and
you therefore won't get all the filenames in a single field entry from
FieldStorage. Instead, you'll get a single entry for each filename in
the FieldStorage object with a value of "on" (or whatever the HTML
forms standard says) associated with it, if the checkbox for that
filename was selected.

What you need to do is to choose a common name for all the checkboxes
and then to put the filename into the "value" attribute for each
checkbox, like this:

  print '<input type="checkbox" value="%s" name="files"><a
href=%s>%s</a></td>'% (filename, fullname, filename)

Then, under the entry for "files" (in this case) in the FieldStorage
object, you'll get a list of filenames whose checkboxes were selected.
