Please could monks point out problems with the following subroutine. I've tried to make the code self-explanatory. 


sub Prioritise_requests {

  my $input_directory = @_;

  my $input_directory_lowest = $input_directory."1";
  my $input_directory_highest = $input_directory."2";


  opendir (LOWEST, "<$input_directory_lowest");  #opendir fix
  opendir (HIGHEST, "<$input_directory_highest"); #open dir fix (previ
+ously just open)... see messages below for details

  my @lowest_priority = <LOWEST>;

  my $request_of_interest = 'none';


  foreach (@lowest_priority){    # foreach low priority request

    my @highest_priority = <HIGHEST>; # fill high_priority array

    if (@highest_priority) {  #  If there are elements in the array 
      #Do nothing
    }
    else {
      $request_of_interest = $_;
    }


    if (@highest_priority) {
      foreach (@highest_priority){   # foreach high priority request
    $request_of_interest = $_;
    return  $request_of_interest;
      }
   return  $request_of_interest;
    }
  }
}

Update: Will the $request_of_interest contain the directory location as well as the file name. (that is what I want it to do).
