Still problems with multicol the info at http://www.ctan.org/tex-archive/help/Catalogue/entries/multicol.html does not say enough.
to repeat my situation: I have a twocolumn koma-book document I have selected twocolumn in document>page I have added in the preample \usepackage{multicol} in order to avoid an empty page which is inserted with the twocolumn selection (as recommended on this list, thanks again) xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx here should come a onecolumn-part \begin{multicols} xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx \end{multicols} and here twocolumn again xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx LaTeX Error: \begin{document} ended by \end{multicols}. \end{multicols} Your command was ignored. Type I <command> <return> to replace it with another command, or <return> to continue without it. If I use \begin{multicols}{1} I get no error, but the onecolumn part is put in the right column of my basic setting twocolumn in document>page According to Herbert, multicol is a separate prg and has nothing to do with the twocolumn setting. Where is my mental blackout? Wolfgang
