Looks like a PHP error to me.

pppppp

<?php

$query = "select * from dil_logins WHERE userID='".$_GET['userID']."'";

$result = mysql_query($query);

if (!$result)
{
die('DIEEEEEEEE'.mysql_error());
}

echo "HEY : ".$query;

$row = mysql_fetch_array($result);

$userID=$row["userID"];
$username=$row["username"];
$password=$row["password"];
