Okay, Im trying to set a captcha up, However with this code in, it breaks.

if(isset($_POST["captcha"]))
    if($_SESSION["captcha"]==$_POST["captcha"])

When i do it with out it, the page works, but the captcha is letting incorrect submits through.

Parse error: syntax error, unexpected '"', expecting T_STRING or T_VARIABLE or T_NUM_STRING in /hermes/waloraweb085/b2027/moo.lutarinet/jointest.php on line 71

<?php

$pagetitle = "Home";

$checkrank = 0;

include ($_SERVER['DOCUMENT_ROOT'].'/header.inc.php');

ECHO <<<END
