Passing them in hidden fields lets user change them at will.
It's ok if you are doing all your validity checks at the end of all
forms, but if you're doing them after each section you need to keep
those variables unaccessible to the user, or re-check them at the end.
You do a imple validity check after each section, asking users to
correct the wrongly formatted fields, and at the total end you re-check
them and give a message asking the user why he tryed to hack the hidden
fields values:)
CGI.pm has sticky form elements, but personally I just hate to print my
html using CGI.pm (and when using it you need to specify with 0 or 1 if
you want previous data keps in form fields)
as of easy way, you can auto_write your hidden fields.. foreach (keys
%param) {print "<input type=hidden name=$_ value=param{$_}>\n";} or
something like this (untested, unchecked)
