General ⇒ Runaway Argument

[ipl]

Hello,
Im getting this error while compiling :

! File ended while scanning use of \@@BOOKMARK.
<inserted text>
\par
l.11 \begin{document}

I suspect you have forgotten a `}', causing me
to read past where you wanted me to stop.
I'll try to recover; but if the error is serious,
you'd better type `E' or `X' now and fix your file.

where do we type `E' or `X' to fix the problem?!!

Typing e to edit a file is bit of a relict from the old days, where compiling a file lasted up to some minutes (to many hours). With x you can abort the compile run, telling latex to close all files.
You can interact with latex either when running it from the command line/terminal, or when compiling with an interactive editor. Texworks is one of them. Quite possibly, it was installed with your TeX distribution.
Most editors run latex with the option -interaction=nonstopmode, which if you imagine the program as a human being would be like: Just do what you think it's best.

As for the runaway argument, the safest and quickest way to find the cause is to prepare a minimal working example. It might take a few minutes, but you will be very happy.

This log file is incomplete, there's no error to find.
Ah, I see your edit. Yes, sometimes already deleting an aux file helps.

Deleting an aux file did solve my similar error. Thanks!
