I downloaded the validation.php and the demo.php page. I saved the demo page to my dev environment so that I could try to get it to work and understand what was happening before I implemented it in my page
When I display the test page, all of the fields show "<?=$fields['email']?>" in them instead of being blank. I tried replacing the "<?=" with "<?php", and I got a error in the field upon refresh that read, "Notice: Undefined index: user_name in C:\inetpub\wwwroot\CW2\demo.php on line 172".
I'm not sure what is going on. A bit of a newbie, and this really has be stumped. Any and all help is greatly appreciated!
