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...
