An HTML POST'ed checkbox variable unsets itself if it is not checked. If you have code that
checks to see if you have been to that form before (e.g. a form that refers to itself) and resets
the checkbox based on that criteria, then you may need to use isset() on a different variable (one
that is not a checkbox). If you only have checkboxes on the form you can check for the submit
button variable.
