Problem solved! Here is what changed in the zips.pm 
sub get_zip {
    my ($self, $city, $state) = @_;
$cityy=   s/\b(\w)(\w*)/uc($1).lc($2)/ge for $city;

#print "$city";
#    return undef unless ($city && $state =~ /^(\d*)$/);
    if (my $zip = $self->single({city_name => $city,state_abbr=>uc($st
+ate)},{columns => [qw/zip_code/]})) {
    return $zip->get_column('zip_code');
}
    return undef;
    return $self->single({city_name=>$city,state_abbr=>uc($state)},{co
+lumns=>[qw/zip_code/]})->get_column('zip_code');
}
