        query( "SELECT ?, email, fullname, level
          FROM members"
      );

      $results->bindParam(1,$member_id, PDO::PARAM_INT);

After keyword prepare delete curly brackets and query. $results = $db->prepare("SELECT ?, email, fullname, level FROM members")

Check the variable name you are binding to query "$memeber_id" - might be typo.

Also I'm not sure if you can put placeholder in query the way you did - check the documentation. http://php.net/manual/en/pdostatement.bindparam.php

Stu,

No worries I also had trouble briefly on this. When it refers to accepting 1 arguement for member_id it is asking for you to have the function accept that. The function it's referring to is the very top one:

function get_member()

So it should be function get_member($member_id)

Hope that helps!

<?php function get_member() { include("connection.php");

try {
  $results = $db->prepare(
      "SELECT ?, email, fullname, level
      FROM members"
  );

$results-> bindParam(1,$member_id,PDO::PARAM_INT); $results->execute(); } catch (Exception $e) { echo "bad query"; }

$members = $results->fetchAll();
return $members;

} This spell checked code,lol, returns the error "your function should accept 1 argument for member_id" I was under the impression the second term in bindParam was this, with the first specifying which param to bind and the third the expected type..
