Just and FYI update, in case someone else has this problem...

The problem was the example was using $PHP_SELF as the form action variable,

of course it has been discussed on this list that in the newer versions
of PHP, register_globals is turned off in php.ini, so $PHP_SELF had no real 
meaning, so no data was actually being passed.  So, just an update to change it 
to:
<form action="<?php echo $_SERVER['PHP_SELF']?>" method=post>
