          if($_POST['email'] == $_POST['email2'])

and when i add the above it return a query is empty.

the full code is below

$editFormAction = $_SERVER['PHP_SELF'];

if (isset($_SERVER['QUERY_STRING'])) {

  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);

}

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form4"))

{

          if($POST['password'] == $_POST['password2'])

          if($_POST['email'] == $_POST['email2'])

  $insertSQL = sprintf("INSERT INTO think_signup (FirstName, Surname, password, email, ContactMethod, TeleNumber, SalaryReq, PositionReq, skills_offered, cv, location) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)",

                       GetSQLValueString($_POST['PositionReq'], "text"),

                       GetSQLValueString($_POST['skills_offered'], "text"),

                       GetSQLValueString($_POST['cv'], "text"),

                       GetSQLValueString($_POST['location'], "text"));
