session_start();

if (!isset($_SESSION)) {

Also needed to remove the unnecessary quotes around SESSION... They were causing an error
The following code works perfectly. Thanks!

<?php
if (!isset($_SESSION)) {
session_start();
}

if($_GET['detail'] == 0){
($_SESSION['detail']=0);
} elseif($_GET['detail'] ==1){
($_SESSION['detail']=1);
}else {
echo "ERROR";
}
?>
sessionDetail is <?php echo $_SESSION['detail']; ?><br>
getDetail is <?php echo $_GET['detail']; ?><br>
httpReferrer is <?php echo $_SERVER['HTTP_REFERER']; ?>
