I am currently trying to pass a hash by reference to a subroutine. The hash is generated by the following query :

    my $existing_users = $dbh->selectall_hashref("SELECT `UserName`, `
+LastAccessDate`, `Ignore` FROM $status_database.`Status`",1);

and prints out the following

    'user1' => {
        'UserName' => 'user1',
        'Ignore' => 'N',
        'LastAccessDate' => '0000-00-00'
    },
    'user2' => {
        'UserName' => 'user2',
        'Ignore' => 'N',
        'LastAccessDate' => '0000-00-00'
    },

This wasn't a problem when I was using the hash globally but now I am trying to pass it to subroutines to organize the code a little better. I am sure this is something simple that I am just over looking. Doing the following simply prints out a number

    send_to_sub(%{$existing_users});

    sub send_to_sub{
        my $existing_users = @_;
        print Dumper(\$existing_users);
        exit;
    }

Help would be appreciated
