Re: $_SESSION as $key=>$value

I read the document 4 times. I understand how it works and now Im excited about applying this to my application, however Im running into a problem. Im recieving an error on my page. I have this in my form. <input name ="fname" type="text" value=" <?php $HTTP_POST_VARS['fname']; ?>" /> and when running, I recieve Notice: Undefined index: fname I also used the example from here http://www.zend.com/zend/spotlight/form-pro-php4.php and I recieved the same message. Any Ideas, to help me break through these barriers? Thanks so much Dan ----- Original Message ----- From: "Ralph" <ralph@nqionline.com> To: "'Daniel J.
