I'm attempting to learn how to use hashes and I'm stuck. I am trying to parse the following file:
614    MNH,16.00|USED,32.00|PB,50.00
615    MNH,36.00|USED,12.00|PB,50.00
616    MNH,96.00|USED,2.00|PB,10.00

[download]

The code I am using to do so is as follows:

#!/usr/bin/perl -w
use strict;
my (@record, @details, @item, $detail, $scottnum, $details, %items);

open(DB, "db.txt") ||
                    die "Could not open the database: $!";

while(<DB>) {
     chomp;
     @record = split(/\t/);
     $scottnum = $record[0];
          @details = split(/\|/, "$record[1]");
               foreach $detail (@details) {
                    @item = split(/,/, "$detail");
                    if (($item[0] ne "") && ($item[1] ne "")){
                         $items{"$item[0]"} = "$item[1]";
                         foreach my $key (%items) {
                                   print "$scottnum\t $key \t $items{$
+key}\n";
                         }
                    }
               }
}


close(DB) ||
               die "Could not close the database: $!";

I keep getting the error: "use of uninitialized value at parse.pl line 19, <DB> chunk 3". I get that error every other line. Could someone please explain to me what I'm doing wrong?
