I use Endnote X. I cannot find the answer to this in FAQ nor in the last 5 pages of forum posts.
This problem of adding unwanted commas as shown above only appears with single author/multiple years and not with multiple authors in one citation eg (JOnes, 2000; Smith 2001) which works perfectly.
I cannot see any problem in Output style manage which looks as follows but maybe i am doing something wrong :
Consecutive Citations by the Same Author
- Omit repeated authors - box is checked
- Separate citations - unchecked and left blank ( just because i was having the same problem when it was checked and included a semicolon.
- Dont omit authors etc - box unchecked.
Many thanks for your help
