General ⇒ I get "missing $ inserted" but don't know why

[Jacare]

Hi,

I use TeXlive in Ubuntu.

I've been compiling a tex file, with the following table.

-------------------------------------------------------------------------------------------------------------------------
...............................................
\begin{table}
\caption{Results of fits for LiF \label{tab:LiFresults}}
\begin{tabular}{| c | c | c | c |}
\hline
Peak & n & Characteristic line & $2 \theta$ \\
\hline
1 & 1 & $K_{\beta}$ & 40.371 \pm 0.026^{\circ} \\
\hline
2 & 1 & $K_{\alpha}$ & 44.879 \pm 0.005^{\circ} \\
\hline
3 & 2 & $K_{\beta}$ & 87.148 \pm 0.308^{\circ} \\
\hline
4 & 2 & $K_{\alpha}$ & 99.510 \pm 0.055^{\circ} \\
\hline
\end{tabular}
\end{table}
..................................etc.etc.
------------------------------------------------------------------------------------------------------------

The compiling works. But I get warnings. Here is an excerpt from the output.

------------------------------------------------------------------------------------------------------------
...............

l.206 1 & 1 & $K_{\beta}$ & 40.371 \pm

<inserted text>
$
l.208 2 & 1 & $K_{\alpha}$ & 44.879 \pm
0.005^{\circ} \\
...............etc. etc.
-----------------------------------------------------------------------------------------------

I get a list of such warning from this and another table. Although the compiling works, the warning are cluttering my output, and I'm afraid that I won't be able to spot an important warning or an error because I don't have the time to check it carefully every time it compiles.

What did I do wrong?

Or is it something wrong with the compiler?

Thanks

Please always provide a full but minimal example [1]. Otherwise specific help is nearly impossible especially when a problem becomes more complicated.

Compilation is far from being flawlessly. And you get no warnings but solid error messages. The commands \pm and ^ (for superscript) only work in math mode.

Source code has to be tagged as such by using the »Code« environment of the foum software

Sorry. My fault. Won't happen again.

Yes! That solved it! Thanks!
