Well I clearly I still dont understand how references and hashes fully.I am writing a module with a subroutine in it.

The subroutine builds an array of a hashes (easy), however I have tried to assign an array to one of those hashes and I'm having no luck. Any ideas? I'm pretty sure it something to do with the way I'm assigning to the hash or reading from the hash Here's the code. 

sub Parse_Constraint_File {

  croak("Parse_Constraint_File <filename>") unless(my $filename = shif
+t);

  my $setup_hash_ref = shift;
  my $open_command = ($filename =~ /\.gz$/) ? "gzip -dc $filename|" : 
+$filename;
  my $rec={};
  my @path_details=[];
  my $i=0;

 open(CONST,"$open_command") || croak("Can't open $filename");
  while(<CONST>){

    # find out the important info:
    if(/Startpoint: ([\w\/]+)$/) { $rec->{'startpoint'} = $1 };
    if(/Endpoint: ([\w\/]+)$/) { $rec->{'endpoint'} = $1 };
    if(/Path Group: (\w+)$/) { $rec->{'path_group'}= $1 };
    if(/Path Type: (\w+)$/) { $rec->{'path_type'}= $1 };
    if(/^\s+Point/.../^\s+slack/ && $setup_hash_ref->{'detail'}){
      push @path_details,$_;
    }

    if(/^\s+slack [\w\(\)]+\s+(-?[\d\.]+)$/) {
      #last field is reached
      $rec->{'slack'} = $1;

      $rec->{'path_details'} = [ @path_details ];

      # if we set a startpoint the only pick those paths
      if (defined($setup_hash_ref->{'startpoint'}) &&
          defined($setup_hash_ref->{'endpoint'})){
        if($rec->{'startpoint'} =~ /$setup_hash_ref->{'startpoint'}/ &
+&
           $rec->{'endpoint'} =~ /$setup_hash_ref->{'endpoint'}/){
          $timing_paths[$i++] = $rec;
          print @path_details;
        }
      }else{
        # otherwise take all points
        $timing_paths[$i++] = $rec;
      }
      @path_details=[];
      $rec={};
    }
  }
  return @timing_paths;
  close CONST;
