To decrement the quantity of an item in the trolley: <?php if( isset( $_SESSION['TrolleyContents'][$myData->RNum] ) ) { $_SESSION['TrolleyContents'][$myData->RNum] -= 1; if( $_SESSION['TrolleyContents'][$myData->RNum] <= 0 ) {
       unset( $_SESSION['TrolleyContents'][$myData->RNum] );
} } ?> I'll leave it as an exercise for you to add or delete X quantity. Cheers, Rob. Thanks. Always willing to learn,
