This is what I implemented? Where did I go wrong?
John

<?php
session_name( 'CCLTrolley' );
session_start();

// Initialize the trolley.
if( !isset( $_SESSION['TrolleyContents'] ) )
{
$_SESSION['TrolleyContents'] = array();
}

if("add" == $_POST['ShopAction'])
{
// Add new entry:
if( isset( $_POST['RNum'] ) )
{
$_SESSION['TrolleyContents'][$_POST['RNum']] = $_POST['RNum'];
}
echo implode( ',', $_SESSION['TrolleyContents'] );
}else{
//Delete an entry:
if( isset( $_SESSION['TrolleyContents'][$_POST['RNum']] ) )
{
# $_SESSION['TrolleyContents'][$_POST['RNum']] -= 1;
# if( $_SESSION['TrolleyContents'][$_POST['RNum']] <= 0 )
# {
unset( $_SESSION['TrolleyContents'][$_POST['RNum']] );
# }
}
}
print_r( $_SESSION );
#phpinfo();
?>
