LyX ⇒ Lyx compilation error

[Dyon]

Hi I have the following code written in lyx preamble. It does not compile anymore and the following error messages are produced.

Code: Select all

1.  \documentclass[titlepage]{
                               csetr-notr}
The document may only declare one class.

2. \trnumber
              {0701}
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.

3. \trnumber{0
                701}
You're in trouble here.  Try typing  <return>  to proceed.
If that doesn't work, type  X <return>  to quit.


4. \trdate
            {\reportDate}
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.

Does someone have any answers for why this is happening ?

Your thoughts will be much appreciated.

Delete the line for document class from your Preamble and instead select that class from the Document>Document Settings>Document Class menu and type the titlepage option in the box right below that. That will clear up the "you can only declare one document class" error. Once that's sorted, post again showing whatever errors remain and I'll see what I can help with.

Thanks StarValkyrie

Well this is what I get after I made those changes.

1. undefined control sequence

\trnumber
{0701}
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.

2.latex error: missing \begin{document}

\trnumber{0
701}
You're in trouble here. Try typing <return> to proceed.
If that doesn't work, type X <return> to quit.

3. undefined control sequence
4. undefined control sequence
5. undefined control sequence
6. undefined control sequence

OK, it doesn't know what to do with the trnumber you've given it in the preamble. Check your package documentation and any templates you have to make sure you've formatted that part correctly.
