Bone headed move guys! In php<4, if a form variable was not set in the form, empty($var) would
return true. Now, empty($var) returns false.
$var = '0'; //php4 sets $var to 0 from a form even if it was not set on the form
empty($var) evaluates to TRUE in php<4
empty($var) evaluates to FALSE in php4
Argghhh!
