Strictly speaking, just
use strict;
Beyond that, just note the error messages
that adding this generates, and go from there.

Did I touch a nerve here or what?
Ge, all of this totally is confusing me,
So you know where I am coming from, I'm taking
a second on-line CGI/PERL class that leaves a lot to be desired (if anyone knows
a good up-todate on-line class, please let me know!)
I will move up to learning CGI.pm, b

When using strict, you must make sure all of your variables are declared
within the proper scope. This means that all variables must either be made
lexical, by using my (restricts scope to current code block), fully
qualified using a package name (i.e. $package::varname), or declared as

In this case, you correctly localized the $key that you were using, but not
the actual %FORM_DATA itself. Much like you did "my $key", simply add

Hello,
I am using MacPerl here.

In my library I have %FORM_DATA declared,

Line 9: Global symbol "FORM_DATA" requires explicit package name.
How can I avoid the ab
