I believe the same idea Matt posted is true for this line:
if ((!$_POST['fname']) || (!$_POST['lname']) || (!$_POST['company'])
|| (!$_POST['title']) || (!$_POST['degree']) || (!$_POST[
'school']))
I am out of reach of a php processor, but I believe if a form submits
these, without populating them, the values of these will be ="". I
generally use
if(!strlen($_POST['fname']) )
{
// You forgot to enter a first name
}
