First point, the <input /> fields should be declared INSIDE the <form>
so that when the submit button is clicked the current values of the
selected items are sent to your processing script. Declared outside, as
you show above, means that they are purely cosmetic rather than
functional.

Nearly there, but what is '$QUESTION_NOS_FROM_THE_ARRAY'? Instead of
that, modify Jeff's example to match your field name, 'checkbox[]':
