Member Update Always Calls Blank Record to Edit

I'm definitely a noob at PHP/MySQL.  I've been buying and reading books, etc. but I can't seem to get the memberUpdate form to return anything except a blank record when selected from a dropdown link after the member logs-in.  I've followed the instructions in DW5.5 The Missing Manual a dozen times.  Even though I believe I'm supposed to filter for a Form variable, I've played with Recordset filter until I'm blue in the face; trying URL param, Form variable and Server variable - all of which test just fine when I click the TEST button and enter a test value, but when I run it from the home page, through the log-in (on the homepage) to the Edit Profile dropdown link, it always shows blank fields, rather than that of the logged-in member.  Oh, I am using the member's email as the primary key in the database.  Please and thank you for any help you can be.  Here's the DW-generated PHP code from the memberUpdate file:

<?php require_once('../Connections/iama_test.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")

    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;   
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
