I am writing a text using the package geometry. for the 4th and 5th chapter the topmargin should be changed. but I get the error message that \geometry{tmargin=10mm} can only be used in the preamble.
using \topmargin is not easy because the tmargin of the geometry package and \topmargin are totally different....
ist there a way to use \geoemtry- commands in the text and not only in the preamble?

attached an example
