Hi I'm trying to use a command with an optional argument in Lyx. I'm not very experienced in Latex, but I found an example which I put in the preamble.
\newcommand{\example}[2][YYY]{ Mandatory arg: #2; \\ Optional arg: #1. \\ } When I use it with one argument, it works nicely... but when I give two arguments it still uses the "optional" argument. What's going on, i.e. what am I missing here?
