Hi and thanks for excellent forum!
I am attempting to use bibDesk with LyX. I save the file in bibDesk (text encoding Unicode UTF-8), import it in lyx with style plain, and change the bibliography style to natbib.
For the citations I then have a numerous alternatives of the from (Author, year), "author, year", etc.
However when generating the pdf the citations gives me the following output:
option Mulazzani et al. (2013): output (author?)
option (Mulazzani et al. 2013): output 
option Mulazzani et al. 2013: output (author?) 1
option Mulazzani et al., 2013: output 1
option Mulazzani et al.: output (author?)
option 2013: output (year?)
option (2013): output [(year?)]
Any help would be greatly appreciated, thanks!
