retain radio button value on validation fail

retain radio button value on validation fail

okay I'm stuck on something. I built a form with textfields and radio buttons. I have it set up that if a user submits the form, and it fails validation ( they left a field blank ) the form retains the info they entered into the text areas. I want the same thing to happen with the radio buttons but I can't figure out how to make that happen. I don't want a default radio button to be initially displayed...just the one that they chose before they submitted (assuming that validation failed)

// just initializing my variables here
$msg_to_user = "";
$edate = "";
$time = "";
$desc = "";
$locat = "";
$outpt = "";
$region = "";

// here is where i am doing my validation checks
if ($_POST['edate'] != "") {

$edate = $_POST['edate'];
$time = $_POST['time'];
$desc = $_POST['desc'];
$locat = $_POST['locat'];
$outpt = $_POST['outpt'];
$region = $_POST['region'];

if (!$time) {
$msg_to_user= '<font color="FF0000">Please enter an event time.</font>';
} else if (!$desc) {
$msg_to_user= '<font color="FF0000">Please enter an event description.</font>';
} else if (!$locat) {
$msg_to_user= '<font color="FF0000">Please enter an event location.</font>';
} else if (!$outpt) {
$msg_to_user= '<font color="FF0000">Please enter output message for email.</font>';
} else if (!$region){
$msg_to_user= '<font color="FF0000">Please choose a region.</font>';
} else {
$msg_to_user= '<font color="FF0000">all done.</font>';
