Problems processing a form; please help!

Hello all, I have a few questions about processing a form. Yes, I know, I probably should RTFM, but I have to have it running at the end of the day...so please, please help me out. Thanks! Q1. <form name="polls" action="polls_process.php?" method="get"> When I submit the form (from polls.php) and process the form (with polls_process.php) the active page becomes polls_process.php (just processing, no output, empty browser screen). But I don’t want to change the page! I want to stay on polls.php. Do the processing, but stay on polls.php. Is this possible? polls.php?a=1&b=2&... ---> polls_process.php <processing> <--- polls_process.php polls.php?a=1&b=2&... I don't want to loose a=1&b=2&... on polls.php... Q2. Should a use get for retrieval only, and post in other cases? (updates) Q3. Should I always use $HTTP_GET_VARS['var'] and $HTTP_POST_VARS['var']? The reference $var also works fine. Or is this only necessary when I use both get and post action in one script? Q4. I often see the @ in front of $HTTP_POST_VARS['var'] (@$HTTP_POST_VARS['var']). I found out that @ mean silent execution. But what could go wrong with $HTTP_POST_VARS['var']?
