of course. You should change the title of your question accordantly.\chaptermark
), and code that should be left to packages (you includegeometry
and set the page dimens directly). Start again with a minimal document.slashbox
package, and is\limpsum
intended to be\lipsum
? Once I remove theslashbox
package, add thecalc
package, and correct\limpsum
, your example compiles for me. Please provide a [MWE]((meta.tex.stackexchange.com/questions/228/…)) that actually illustrates the problem.
