Authorless references and in-text citation


this is the problem using endnote 9. say I want to use references of the same author in different years but does not want to show the author’s name inside the bracket the following result appears:   (2001;,2003) but I want to them to show (2001,2003). It is already there in endnote x1 but how can i correct it in endnote 9?

Thanks in advance.
