Because register globals is disabled you have to use $_SERVER['PHP_SELF'],
that's covered in the manual.

That's because the first time you run it you have not submitted a form yet so
it's undefined.
Various ways to get around this, most straight forward (IMO) being:
if (isset($_post['answered'])) { echo $_post['answered']; }

That's because register_globals is off :)
The PHP_SELF value is contained in the $_SERVER superglobal array and you
may access it anytime, everywhere as $_SERVER['PHP_SELF'].

This is not an error you see but a Notice or Warning that you are using a
variable (or an array index) that has not been defined yet. While this is
not necessary in this siziation it might point out a possible source of
problems under other circumstances, allowing you to spot why your script
doesn't work as expected.
You could either
if (array_key_exists('answered', $_POST))
to avoid the warning, or
error_reporting(E_ALL & ~(E_NOTICE|E_WARNING))
to switch off notices or warnings for this script, if you are prepared to
do so...

It's not difficult at all, it's just slightly different to ASP. You'll love
PHP, promised...

Re: [PHP] Form variables not working
Because it isn't? Instead of echoing $PHP_SELF, echo
$_SERVER['PHP_SELF']. With the $_POST problem, it's complaining that
you're using a variable that isn't defined. Use?
if(array_key_exists('formfieldnamegoeshere',$_POST)){
print $_POST['formfieldnamegoeshere'];
}
?>
