UPDATE: SOLUTION PROVIDED

I have a written a working Perl script (my first one). The interpreter complains when I turn on 'use strict'. I get the following error message: "Global symbol $files requires explicit package name at...line 19...line 20...line 24".

My code:

#!/usr/bin/perl
use warnings;
use strict;

my @files;
my $downloadpath = "/home/content/c/r/e/creatingzion/html/downloads";
my $timestamp = time();
my $modified_time; #[9] in the list of file attributes.
my $age_of_file;
my $time_to_live = 3600;

#return a list of all the mp3 files in the downloadpath
opendir(DIR, $downloadpath);
@files = grep(/\.mp3$/,readdir(DIR));
closedir(DIR);
#end comment

#compare each file's last modified time with the current time and dele
+te any files older than the time to live in seconds.
foreach $files (@files)
{    $modified_time = (stat($downloadpath."/".$files))[9];
    print $modified_time;
    $age_of_file = $timestamp - $modified_time;
    if($age_of_file >= $time_to_live)
        {unlink($downloadpath."/".$files);}
}
#end comment

The only thing I can think of and only thing my research indicates is that I need to use a lexical variable. But I'm doing that already.

UPDATE: Thank you both for you help.
