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
