I'm having trouble with the LaTex generator on your site. If I try to enter a slightly corrected line of LaTex in the process of correcting the equation, your site allows maybe 2 or 3 corrections and then ignores any further submissions, repeating the same symbols even though I errased the LaTex portion of those symbols. I find this extremely annoying. If that is your intend to prevent abuse, then please have the system tell you this with a warning message.

Perhaps I over used the system when trying repeatedly to have it print out "b $$\sigma$$ t ", where sigma is the greek letter and t is the english letter. No matter what I seem to try the system does not want to print out a two letter subscript consisting of one sigma and one letter t.

Would appreciate a little help here.

Other than that, thank you ever so much for providing an easy code for generating math.

Thanks.

What, like this?

$$b_{\sigma t}$$

(Monique, you don't need the extra brackets unless you're trying to force it to align both superscripts and subscripts.)

Mike,

I see two possibilities.

1) You're entering invalid TeX, and you're not sure why the output isn't what you expected. If so, please let us know what TeX you're using, so we can debug it.

Ah, but does it then include a space or not? When I did it before it didn't.. let me try a spacer:

$$b_{\it \sigma~t}$$

 Recognitions: Gold Member Science Advisor Staff Emeritus not so pretty but it works :P
 You're right, it doesn't include a space by default, since that's usually not what people intend. With double subscripts, people usually intend $$b_{\sigma t}$$ or sometimes $$b_{\sigma_t}$$ but usually not $$b_{\sigma~t}$$ (And by the way, you don't need to italicize any subscripts unless they're supposed to be English words, so it gets things like ligatures correct.)
 Recognitions: Gold Member Science Advisor Staff Emeritus You are right, I am still learning too [:D] I like the sight of $$b_{\sigma_t}$$ I guess that is what mike wanted to see?
 A question. How do I change the default numbering in a list such as: Code: \begin{enumerate} \item First item \item Second item \item Third item .... \end{enumerate} So that the first and second items are numbered, but all remaining items are listed with letters: 1. First Item 2. Second Item A. Third Item. etc...
 $$\begin{quote} \begin{enumerate} \item First item \item Second item \renewcommand{\labelenumi}{\Alph{enumi}} \setcounter{enumi}{0} \item Third item \item Fourth item \end{enumerate} \end{quote}$$

Thanx, worked perfectly.
