This is technically invalid for PHP -- all your form field names should conform to the rules for PHP variable names, so it would be better to use name="q1", name="q2", etc.

The reason is that if you were to turn register_globals on, PHP would try to create global variables using your field names, and $1, $2, etc. are not valid variables. Whilst PHP *may* get this right if you have register_globals turned off, there is no absolute guarantee that $_POST['1'] etc. will be handled correctly.

Cheers!
