Master X Detail control

Good morning my friends. I need help building an order control where I can see the order number, the items ordered, the quantity of each item, the value of each item, the total value per item and the total order value. My model with orders table and items table is already built, Screens for viewing, inserting and viewing as well. But I can't set up the completed order control screen and total the values including the option to cancel the order.   Tanks

We need a bit more info before we can help. At what part are you stuck? Can you retrieve in a microflow from the Order retrieve the items ordered? Because then creating the total order value is not that hard. So Edit your post and tell us where you get stuck.
