Page Layout ⇒ Different Margins for every odd page

[0Jam]

Dear people of the internet,
I would like to have every second page of my rather large document have different margins, top and bottom.
I have tried editing the geometry package options, but no luck, I get different errors each time:

Code: Select all

\ifthenelse{\equal{\value{Hilf}}{0}}{\geometry{top=1.5cm}}{\ifthenelse{\isodd{\value{page}}}{\geometry{top=1.5cm}}{\geometry{top=.5cm}}}

I hope you can see what I've tried to do here, the value "Hilf" is merely unequal to 0 once the document starts.
\ifthenelse has helped me out a lot, but I've read the texdoc documentation on the geometry package and it doesn't seem like you can do anything other than arithmetics inside the arguments of the package.

Code: Select all

\usepackage[left=2.5cm,right=2.5cm]{geometry}
\geometry{
	top={\ifthenelse{\equal{\value{Hilf}}{0}}{1.5cm}{{\ifthenelse{\isodd{\value{page}}}{1.5cm}{.5cm}}}},
	bottom=1.5cm,
	footskip=1.4cm, nomarginpar
	%top={\ifthenelse{\isodd{\value{page}}}
	%{2cm}
	%{5cm}}
}

I don't want to have to use \newgeometry and \restoregeometry every second page, there has to be a better way

Thank you!

Also there needs to be a command, I can not do this manually using \newgeometry and \restoregeometry as the ToC is just one big thing.

Code: Select all

\ifthenelse{\equal{\value{Hilf}}{0}}{}{{\ifthenelse{\isodd{\value{page}}}{\newgeometry{top=.5cm}}{\restoregeometry}}}

something like this gets me the error: "You can't use `\relax' after \the. \ifthenelse{\equal{\value{Hilf}}{0}}"
