For checkbox's I like to have a HIDDEN checkbox.
<INPUT TYPE=hidden NAME=blah VALUE="">
<INPUT TYPE=checkbox NAME=blah VALUE="1">
<INPUT TYPE=checkbox NAME=blah VALUE="2">
<INPUT TYPE=checkbox NAME=blah VALUE="3">
With the hidden name and value, I'll always have at least a blank form
variable passed.
