misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

Is there a specific miktex (mpm.exe) package I need to see installed?

Rds,




You need AMS math loaded.  In LyX, go to Document  Settings...  Math 
Options and check Use AMS math package.


Also, when you enter the command, be sure to start the braces with \{ 
rather than just {.  If you literally type \hdotsfor{3}, say, what 
you'll end up with in LaTeX is \hdotsfor\{3\}, escaping the braces, and 
then LaTeX will complain about a missing or invalid numerical argument. 
 If you type \hdotsfor followed by \{, LyX will convert \{ to a matched 
pair of braces with an input widget (rectangle) in between them, which 
is what you want.
