Math & Science ⇒ Problem with Typeset on MikTex and solving it

[Achava]

I have a problem which I cannot solve using MikTex in Windows 10 Home. I typed in the first usepackage program on page 41 of the Stefan Kottwitz book Beginner's Guide. I then ran Typeset in MikTex and the code failed telling me there was a problem with the environment. I know very little about the Windows operating system and haven't found a way to solve the problem. How do I solve it?

Please copy the example you have problems with. I don't know what is on page 41.

Use texworks (which is installed with MikTeX) to compile your first documents.

Here is the code I used

Code: Select all

\documentclass {article}
\usepackage {xspace}
\newcommand {\TUG} {\textsc {TeX Users Group} \xspace}
\begin {document}
\section {The \TUG}
TheTUG is an organization for people who are interested in \Tex\ or \LaTeX.
\end {document}

Here is the error this time

?

There is nothing about environment this time which I do remember the first time I ran it. I don't understand this error either.

Simple typo: You've used \Tex, but the correct spelling of the command is \TeX. Note, TeX is case-sensitive.

BTW: Please use code tags (or the "Select code" field) to mark code in you postings.

[Achava]

Thank you. The code now works.
