Unable to use the send_offer function properly

I have tried to use the data from the $results variable in the send_offer function but I am unable to get it to work properly. I keep getting the following error message:

"Bummer! Doesn't look like you are passing the correct values."

Can anyone see what is wrong with my code?

Thanks,

Kevin

index.php 
<?php
include "helper.php";

try {
    $results = $db->query(
        "SELECT member_id, email, fullname, level FROM members"
    );
} catch (Exception $e) {
    echo $e->getMessage();
}
//add code below this line

$loop = $results->fetchAll(PDO::FETCH_ASSOC);

$member_id = $loop->member_id;
$email = $loop->email;
$fullname = $loop->fullname;
$level = $loop->level;

send_offer($member_id, $email, $fullname, $level);

This looks good so far! The only thing missing is looping through the results of $results->fetchAll. fetchAll returns a collection of PDO objects, which can be treated just like an array.

So for each member in the result set, you need to set $member_id, $email, $fullname, $level, and call send_offer:

$members = $results->fetchAll(PDO::FETCH_ASSOC);
foreach ($members as $member) {
 . . . 
}

Ok, that make sense, I hadn't thought that it would need to be looped through a foreach loop. I have added this into my code now and it was successful, thanks very much for your help!
