The isset or empty, it's return a boolean (true 1, false 0), the isset will return true if the variable will have been initiated, the empty will return true if the variable is empty, but for that the variable need to be initiated. You can do it in a many ways, like:
$msg.= (isset($_POST['mort']) && !empty($_POST['mort']) ? "The mortgage amount is $mort\n" : " "); or $msg.= ($_POST['mort'] == '' ? "The mortgage amount is $mort\n" : " "); or $msg.= (strlen($_POST['mort']) > 0 ? "The mortgage amount is $mort\n" : " "); Yuri Yarlei.
