I'm trying to splice out a value from an array that is also in a hash, and I keep getting, 'Global symbol "@array of lists" requires explicit package name...' I hate having to ask for help, but I've been reading and racking my brain for 2 days... Any help would be very appreciated. 
my %array_of_lists = ('1' => \@list3, '2' => \@list4, '3' => \@list899
+);
  #my @array_of_lists = (@list3, @list4, @list899);
  ##Set my hand
  my $my_pocket = "AcAs";
 
 #printf("\n\n@array_of_lists\n\n");
  #My cards
  my $my_card1 = substr($my_pocket, 0, 2);
  my $my_card2 = substr($my_pocket, 2, 2);
  printf("$my_pocket");
  
  #for (my $z = 0; $z <= 100; $z++
  #{
  for my $a ( 0 .. scalar(keys %array_of_lists))
    {
        #The loop will iterate through each element (hand of current h
+andlist)  of the current row and remove any
        #hand that contains the cards assigned randomly above.
        for my $b ( 0 .. $#{$array_of_lists->{$b}} )
        {
            #If the first card of the random hand above equal the firs
+t card in the element I am currently on, then remove the element from
+ this handlist by
            #splicing it out. Or if the first card of the random hand 
+above equal the second card of the element (hand) I am currently spli
+ce it out.
            if (substr($my_pocket, 0, 2) eq substr($array_of_lists->{$
+a}{$b}, 0, 2) || substr($my_pocket, 0, 2) eq substr($array_of_lists->
+{$a}{$b}, 2, 2))
            {
                $array_of_lists->{$a} = splice(@{$array_of_lists{$a}},
+ $b, 1);
            }
            elsif (substr($my_pocket, 2, 2) eq substr($array_of_lists-
+>{$a}{$b}, 0, 2) || substr($my_pocket, 2, 2) eq substr($array_of_list
+s->{$a}{$b}, 2, 2))
            {
                $array_of_lists->{$a} = splice(@{$array_of_lists{$a}},
+ $b, 1);
            }
        }
    }
