When I use IEEE - Reference Order style for my Bibligraphy table I get the references numbers OK. Well formated as .
But when I switch to Alphabetic Order style I lose the numbers, and in their places always is [BO]
What should I do?
As this style does not come with Word, you probably downloaded it somewhere. Didn't it come with instructions at the download site?
Well, the FAQ on that first link seems pretty straightforward:
Q: Why do I get 'BO' between brackets instead of a number when using the IEEE - Alphabetical style*?
A: The IEEE - Alphabetical* style requires the BibWord Extender tool to function properly. This tool will decide the on the numbers to place instead of 'BO'.
