problem is that the new line does not print the correct value of $page
(its supposed to change every pass through the perl code),
CGI has "sticky" fields. The value that was just submitted has priority
over the the value specified by -value.
This is usually a good thing. If someone's submission is malformed in one
field, and you need to tell them to change it and resubmit, you want
the new page to retain their previous selections rather than forcing them
to start over with the original defaults (although this argument is less
compelling in the case of hidden fields.)
To change this default behavior for an individual field, specify
-override => 1
You can also turn it off globally by using -nosticky when CGI is "use"d.
I have
tried enclosing the contents of the hidden() command in "{}" but this
made no difference. I am not sure what the role of these brackets
are, some syntax shows them present and other forms of the syntax
shows them absent.
CGI offers an absurd amount of flexibility in how parameters are passed
to it's methods/functions. The list-vs-hash is part of that. It shouldn't
change the behavior.
