I am working on creating a module for experience. I am came to a standstill while trying to pass variables from one subroutine to another. I have tried many different ways but I am still stuck. This is what I have... 
sub new {
    my $package = shift;
    my @fileArray = 'counter.pl';
    if (@_) {
        my $fileArrayR = $_[0];
        @fileArray = @$fileArrayR;
    }
    test(\@fileArray);
    totalBandwith(\@fileArray);
    return bless({}, $package);
}

sub test {
    my $self = shift;
    my $test = $_[0];   # <-- Line 53
    my @tests = @$test;
    foreach my $line (@_) {
        print $line;
    }
}

This is not what I actually want the script to be (I don't want it to print, for ex), but I am just tryint to test it. I keep getting Can't use an undefined value as an ARRAY reference at Counter.pm line 53. from the command prompt when I try to run it. Any help would be great, thanks.
