LyX ⇒ IEEEtran | Roman Numbering for Appendices

[peytonator]

Hi,

I'm using the IEEEtran document class. When I add multiple appendices (using appendix environment), their headings are not numbered. To add numbering, the IEEEtran how-to doc (http://www.ngi2009.eu/IEEEtran_HOWTO.pdf) says I should add the \romanappendices command.

I tried adding

• \romanappendices to the preamble
• \romanappendices ERT to the document before, after and inside the appendices
• romanappendices to the class options

... none of which worked.

How do I correctly number the appendix headings (A, B, C, etc.)?

Thanks
