problem with counter

[Anon]

hi all

can someone tell me what's wrong with this code. It doesn't increment the value of $count. It works on a Mac but not on a PC !

$sql = ("SELECT member_id, member_password, member_first_name, member_last_name from fnd_member where member_email = '$email' AND member_password = '$code'");
$result = mysql_query($sql);
$row = mysql_fetch_array($result);
$first_name = $row["member_first_name"];
$last_name = $row["member_last_name"];

$num_users = mysql_num_rows($result);


if($num_users == 0) {

$count == $count++; 
header("Location: http://www.foodndrink.co.uk/test/login.php3?count=$count&requested_url=$requested_url");

$count == $count++ is wrong. Just use
$count++;

$count ++ means $count = $count + 1;
