%FORM_DATA (which I am guessing is defined and/or created in libcgi2.pl)
isn't explicitly put into a package (which you correctly do with the $key
scalar, using 'my'). Since you are requiring the library, it is getting
included into the current file, for which you are usng the strict pragma,
but it's complaining about things in the library that are not properly
defined using the stricter syntax.
Want to make your life easier? Use CGI.pm. It handles all of this form
input stuff for you automatically, and many other things besides, and
lets you focus more on your application logic than trying to decode
headers, HTML parsing, etc. And then send email to
[EMAIL PROTECTED] so you can get on the beginning Perl CGI
for beginners list.
