in reply to symbolic ref error

You shouldn't be using symbolic refs in the first place!

Maybe you should back up a step. Can you describe your goal without going into implementation?

    I know it looks messy but what I am trying to do is put a value into an array that is named after the conditions in which the value was taken. Here is more: 
    $seq = 'KLLS3';
$point = 'weight';
$index = 4;
$mean = 1.443;

sorting($seq, $index, $point, $mean);

sub sorting
{

if ($_[0] eq "KLLS3_LT.V4_0")
{
if ($_[1] == "1")
{push @{{$_[2]}{$_[0]}{$_[1]}}, $_[3];}
}

      ...put a value into an array that is named after the conditions...

      Is there any reason why you can't use a hash array instead of a symbolic reference to a regular array (and use strict)? E.g.:

      my $seq = 'KLLS3';
my $point = 'weight';
my $index = 4;
my $mean = 1.443;
my %hash;

sorting($seq, $index, $point, $mean);

sub sorting
{

  if ($_[0] eq "KLLS3_LT.V4_0")
  {
    if ($_[1] == "1")
    {push @{$hash{$_[2]}{$_[0]}{$_[1]}}, $_[3];}
  }
}

        I'm not familiar with using a "hash array". Where can I learn more? I have all the O'Reilly books on Perl. In your example, how would you retreive the values from the numerous arrays?
