  1. I'm hoping for some kind assistance for this old brain. I'm trying to change the cliché "You can't teach an old dog new tricks"... OK, I understand creating of the $okay flag variable as TRUE and then the introduction of the empty() function with if (empty($_POST['email'])) {print '<p class="error"> Please enter your email address.</p>'; $okay = FALSE. But what I don't understand is if the user does not enter the necessary information and then the $okay value changes to FALSE, what keeps the success message from printing? So the flag variable has changed from TRUE to FALSE, how does that make the success message not print? To quote the book "In that case, this conditional will also be FALSE so the message won't be printed". Obviously it works, I'm just not getting why... Any help would be much appreciated. Perry
