LyX ⇒ Problem with amsbook and normalsize

[TXLogicTA]

I'm getting an annoying error message when I try to change the text size of my chapter headings to the default text size when using amsbook. The resulting LaTeX source code is:

\chapter{{\normalsize INTRODUCTION: WHAT SOME THINK}}

Here's the error message:

---------------
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
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.

The problem does not arise for other document classes. What's wrong with amsbook? Is there a simple fix? This is the last thing I need to resolve to be done with my thesis!

Hi,

welcome to the board!
You could fix it by \protect:

Code: Select all

\chapter{{\protect\normalsize INTRODUCTION: WHAT SOME THINK}}

Thanks, Stefan! That got rid of the error.

However, it created a new problem. This is not a problem for my purposes, but it might not be acceptable for others who try this fix.

For some reason, even though I have the font set at 11pt, everything went to 10pt, throughout the entire document. Should this be happening?

oh no wait... that was a mistake i made. everything's perfect now!

It depends on how you've set the font size. A document class option 11pt should work.
