## math commands outside math environment

Hi

I've just stumbled on TeXStudio. Looks wonderful.

I'm generating TeX output from some mathematics software. I figured out some of the issues using help from this forum by enabling manually some CWL options, including all the ams* stuff, and mathtool, and also the latex-mathsymbols.

This has got me a bit stumped though. It does not like the \sigma in this lot:

The error is "math command outside math env". If it is INSIDE an {array} section, it is happy though?

Can anyone help?

Many thanks

• the syntax checker can't handle the \text{...} command correctly.
And then you started a math env inside a \text option which disables the
surrounding math env.
Alternatively you could place \sigma before the \text command.

Thanks! Got it working!
