Sounds like you need to stick my before every variable.

when you are using strict (which you always should), variables must be declared this way.

Well, that's not strictly true. When using strict you must either pre-declare variables or use their fully qualified names.

You can pre-declare lexical vaiables using my or package variables using use vars. You can also use our if you're using Perl 5.6 or later.

You can use package variables without pre-declaring them by giving them a fully-qualified name, e.g. $main::scalar, @main::array or %main::hash. These can also be abbreviated to $::scalar, @::array and%::hash.
