SESSION array problems

[tedd <tedd@xxxxxxxxxxxx>]

Hi gang:

Apparently, there's something going on here that I don't understand 
-- this happens far too often these days.

Here's a print_r($_SESSION); of the session arrays I'm using:

    [user_id] => Array
        (
            [0] => 6156
            [1] => 7030
            [2] => 656
        )

    [first_name] => Array
        (
            [0] => Diane
            [1] => Fred
            [2] => Helen
        )

    [last_name] => Array
        (
            [0] => Cable
            [1] => Cago
            [2] => Cahalan


The following is how I tried to access the data contained in the 
$_SESSION arrays:

$num_users = count($_SESSION['user_id']);

for ($i = 0; $i < $num_users; $i++)
	{
	$last_name = $_SESSION['last_name'][$i];
	$first_name = $_SESSION['first_name'][$i];
	echo("<p>$last_name, $first_name</p>");
	}

The only thing that came out correct was the first echo. The 
remaining echos had no values for $first_name or $last_name.

What's happening here?

Cheers,

tedd


PS: I'm open to other suggestions as to how to do this.
