Adding references in a Word document now seems very easy. Though I cannot add a numbered reference before one I've already added.



For Example:
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Maecenas porttitor congue massa. (1)


With (1) the first reference. Now I write an extra sentence before this one, so this should be (1) and the previous should become (2).


For example:

Donec hendrerit, felis et imperdiet euismod, purus ipsum pretium metus, in lacinia nulla nisl eget sapien.(1) Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Maecenas porttitor congue massa. (2)


Instead, this is the result:
Donec hendrerit, felis et imperdiet euismod, purus ipsum pretium metus, in lacinia nulla nisl eget sapien.(1) Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Maecenas porttitor congue massa. (1)


Does anyone know how to solve this problem?
