Echo out the variable....
echo ( $_POST['fname'] );
All the notice is telling you is that $HTTP_POST_VARS['fname'] doesn't exist, which it isn't if you haven't posted it to this page.

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

Daniel,
Rather than sending them to a new page to validate the form and then sending them back if a field is invalid, do the error checking from the same script.
Here's an example, a bit simple but just to give you an idea.
For a better explanation, you should read this article which elaborates on this method:
http://www.zend.com/zend/spotlight/form-pro-php4.php
<?php
if($HTTP_POST_VARS){
// check for required fields if(!HTTP_POST_VARS['name'] || !HTTP_POST_VARS['email']) $error_message = 'You did not provide all required fields' }
// any other error checking you want to do .... ?>
<?php
// if error, print out error message if($error_message){ echo $error_message; }
?>
<FORM METHOD="post" ACTION="<?php echo $PHP_SELF ?>"> <INPUT TYPE="text" NAME="name" SIZE="20" VALUE="<?php echo $HTTP_POST_VARS['name'] ?>"> <INPUT TYPE="text" NAME="email" SIZE="20" VALUE="<?php echo $HTTP_POST_VARS['email'] ?>"> and so on....
<INPUT TYPE="submit" NAME="process_form" VALUE="Submit">

Is this valid to iterate over a form variables.?
foreach ($_SESSION as $key=>$value)
and another question, do I need this <form action="scripts/process.php" method="post"> in my form?
Im really struggling with $_SESSION. Im trying to program smarter and make friendlier applications.
Ive submitted several emails dealing with this function and I apologize for beating a dead horse, so to speak.
I have a form with a few form fields. Im working on an error function that will take the data that was entered and pass it back to the form so that the user will not have to input the data again. If an error is found I use the header function to go back to the form. Im having trouble with passing back the data. Do I in my form setup a $_GET or should I use the $_SESSION to call it. I am also going to setup a few css styles that highlight which field was found in error.
Again, I apologize for my lack of vision and maybe a spark of light will go off, and I will be able to make some connections to get this done.
