Hi
I am using Revtex4 document class and have included a bibliography, selecting the correct style for my document. Also I have selected natbib and numerical.
When I 'compile' i get the following error message
The package natbib has already been loaded with options: [sort&compress] There has now been an attempt to load it with options [numbers]
Any advice on how to get this to work, as you cant not select a cite style.
Geoff
