[Resolved] Accessing arrays inside of $_POST

[silent]

I know how this works, but there seems to be a problem.

I have a fields like this :
<input type="text" name="user[user_name]">

Etc..
(accessed via $_POST['user']['user_name'])

But I have a multi-selectable list box.
(two of them, actually)

They are named like this :
<select name="users[prefs][]">

When I do a print_r($_POST), it shows it correctly.
But it will not allow me to foreach($users[prefs]) or implode(',',$users['prefs'])

What am I doing wrong????
TIA

Show us the code?

And maybe the print_r output...

[silent]

function get_post_array($which) {
  global $HTTP_POST_VARS;
  return $HTTP_POST_VARS[$which];
}

function a_signup_2() {
  global $HTTP_POST_VARS;
  $this->header();
  $profiles = $this->get_post_array('profiles');
  $dob = mktime(0,0,0,$profiles['dob'][0],$profiles['dob'][1],$profiles['dob'][2]);
  unset($profiles['dob']);
  $profiles['dob'] = $dob;
  $grad_date = mktime(0,0,0,$profiles['grad_date'][0],$profiles['grad_date'][1],$profiles['grad_date'][2]);
  unset($profiles['grad_date']);
  $profiles['grad_date'] = $grad_date;
  $profiles['user_id'] = $this->db_last_insert_id();
  $qry = $this->build_insert('profiles',$profiles);
  //This is where I need help
  $affiliation = implode(',',$profiles['affiliation']);
  $this->footer();
}

Here is the output of print_r($_POST)

Array
(
[users] => Array
(
[user_name] =>
[user_password] =>
)

[profiles] => Array
    (
        [name] => 
        [dob] => Array
            (
                [0] => 1
                [1] => 1
                [2] => 1960
            )

        [mailing_address] => 
        [parental_contact] => 
        [college_year] => Freshman
        [major] => 
        [transfer_student] => 0
        [grad_student] => 0
        [grad_date] => Array
            (
                [0] => 1
                [1] => 1
                [2] => 1960
            )

        [afilliation] => Array
            (
                [0] => Reform
                [1] => Conservative
                [2] => Orthodox
                [3] => Reconstructionist
            )

        [past_involvement] => Array
            (
                [0] => None
                [1] => Jewish Camps
                [2] => Youth Groups
                [3] => Jewish Day School
                [4] => Trips to Israel
            )

    )

[Submit] => Continue >>

)

Additional note : I have a date select box that uses the same form name "profiles[date][]" (month is in profiles[date][0] etc.)
and it works fine.. that's weird. Maybe it has something to do with the fact that it is MULTIPLE?

hehe... I am very sleep deprived, and it shows.
I was misspelling affiliation.

I had it as 'affilliation'

Dammit.

Thanks.
