If you have been adding or importing items into a bill section, you may find that the items are not in the order you want and that there are some duplicate references.
The easiest way to get the items into the order you want is to overtype the Reference, as the items will stay in alphabetical (or numeric) order.
If the items are in the right order but the references have gaps or duplicates, or once you have the items in the order you want, right-click on the first item and choose Rereference. This will then change the references as necessary for them to be sequential, in the order they currently appear.
