For some reason, my array @databaseis being set to two undef values after it is used in an innocent-looking for loop... can someone remedy this? I using Perl 5.8.0.

#!/usr/bin/perl

use strict;



use Data::Dumper;
use DBIx::Connect;
use DBIx::Recordset;

my @database = (qw(horse1 SYNDB));

my $r  = '/data/tbone/maldunn2';
my %tbl;


$DBIx::Recordset::Debug = 2;
*DBIx::Recordset::LOG   = \*STDERR;

sub tbl_srch {

    my ($fname, $lname) = @_;
    
    for my $db (@database) {
    while ( my ($table, $fields) = each %tbl ) {
    
        DBIx::Recordset->Search
        ({
          '!DataSource' => DBIx::Connect->to($db),
          $fields->[2]  => $fname,
          $fields->[3]  => $lname
         });

    }
    }


}

sub load_tbls {

    my $database = shift;
    open T, "$r/$database.tblmap-names-email-address";
    while ( <T>) {
    my ($table, @field) = split;
    $tbl{$table} = \@field;
    }

}

warn Dumper(\@database);
load_tbls $_ for (@database);
die Dumper(\@database);
tbl_srch 'John', 'Smith';
