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,
