IE 'Back' Button problem + SELECT dropdowns

Hi, I've managed to get Windows IE to pick up on most of my $_SESSION variables once a user clicks the 'Back' button using the following code in the base form: 'value=<?php if(!empty($_SESSION['rfname'])) echo $_SESSION['rfname']; ?>' However, when I try this approach for a muliple SELECT dropdown box that is loaded by a 'require' statement, it doesn't pass the info. I've tried to isolate the individual components: <?php require("dobdod.fdd"); if(!empty($_PST['bday'])) echo $_POST['bday']; if(!empty($_POST['bmonth'])) echo $_POST['bmonth']; if(!empty($_POST['birth'])) echo $_POST['birth']; if(!empty($_POST['dday'])) echo $_POST['dday']; if(!empty($_POST['dmonth'])) echo $_POST['dmonth']; if(!empty($_POST['death'])) echo $_POST['death']; ?> Btw, the base form calls another form, which displays an error message. Once the 'Back' button is clicked, the base form reappears. [I've also tried putting a <?php . . . ?> around each if(!empty . . .); statement above with same result.] Any ideas what I'm doing wrong? I've been at this one for a couple of weeks, and nothing seems top work. Is it possible to pass the info back to the base form? Tia, Andre
