This is what you recommended.

Is there a reason you're using a comma delimited string? I would recommend using an array instead: <?php session_name( 'CCLTrolley' ); session_start(); // Initialize the trolley. if( !isset( $_SESSION['TrolleyContents'] ) ) { $_SESSION['TrolleyContents'] = array(); } // Add new entry. if( isset( $_POST['AddToTrolley'] ) ) { $_SESSION['TrolleyContents'][$_POST['AddToTrolley']] = $_POST['AddToTrolley'] } echo implode( ',', $_SESSION['TrolleyContents'] ); phpinfo(); ?>

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(); ?>
