I am facing problems with below code. This works with my search criteria 'Technology Phones' and returns correct key "TEC-PH 10001949" which is my requirements. 

#! perl
use strict;
use warnings;
use Data::Dumper;

my %categories = ("FUR-BO 10001798" => 'Furniture',
                  "FUR-CH 10000454" => [ 'Furniture' , 'Chairs'],
                  "OFF-LA 10000240" => [ 'Office Supplies' , 'Labels']
+,
                  "OFF-ST 10000107" => [ 'Office Supplies' , 'Storage'
+],
                  "OFF-AR 10003056" => [ 'Office Supplies' , 'Art'],
                  "TEC-PH 10001949" => 'Technology Phones',
                );
                

#print Dumper(%categories);

print "What is Category code for Technology Phones          | Output s
+hould be : TEC-PH 10001949? \n";


my $categorycode;
my $search = 'Technology Phones';
my @category = ();

foreach $categorycode (keys(%categories)) {
    if(ref($categories{$categorycode}) eq 'ARRAY' and
        grep { $_ eq $search } @{ $categories{$categorycode} }) {
        push(@category, $categorycode);
    } elsif(!ref($categories{$categorycode}) and $categories{$category
+code} eq $search) {
        push(@category, $categorycode);
    }
}

print join(", ", @category) . "\n";

However if I change the search = 'Furniture' I need the output as "FUR-BO 10001798" But I get key value "FUR-BO 10001798" & "FUR-CH 10000454" which is not correct.

Also If I give search criteria as 'Office Supplies' , 'Labels' I want my output as "OFF-LA 10000240".

So $search variable are value/values in my hash and I need to return key as output.

Please help on fixing this. Thanks.
