This one beats me... :) Try one of the 'other', like $SCRIPT_NAME and
see if it works the same...

This one may be easy: are you using the 'name' attributes? e.g. you have
to use something like this on your form:
<input type=text name=whatever ...>
^^^^^^^^^^^^^
THEN you'll be able to refer to that field using $whatever and it will be
included in $HTTP_POST_VARS.

I don't think this will work: you're not actually submiting anything this
way; all you're doing is calling the script on another frame, and that will
probably not send any data along with it... If you want your results to
appear in a diferent frame, you'll have to do it some other way, like
using redirects or something...

I don't see why you want to do that: is the script name to be variable
depending on who is requesting the page? This is probably happening because
you're trying to use a tag ('<?') inside another tag ('<form...>')
If you MUST do it, try this instead:
<?
$script_name = '/cgi-bin/hello.php';
$form = '<FORM ACTION=" . $script_name . "etc...>';
echo $form;
?>
... rest of the form html ...
