Duplicate citations appearing as different numbers
This is probably a really simple fix, but I'm having difficulty with my citations. If I cite the same article multiple times in the same document using insert citation, I would like its reference number to be the same every time. For example, the first article I cite is by Esterling and I cite the same article again on page 6 and page 9. I would like the citations on pages 6 and 9 to be (1) just like on the first page. As of now, every time I enter a new citation it is coded as a new number, even when the article has already been cited in the text. Thus, citations (1), (23), and (34) can all refer to the same article. I'm guessing there is a simple answer, but I've gone in circles trying to figure it out. Thanks!
