Peter, thanks for your help yet again!

OK, so I'm not completely off the mark...

Actually, this part of the code works. I have defined overlays/layers  
and a variable PageBackground and in my doifelse want this

\let\PageBackground\empty
\def\CameraMarks{Camera}
\def\CrossMarks{Cross}

\doifelse{\getvariable{Crop}{mark}{camera}
   {\let\PageBackground\CameraMarks}
   {\doifelse{\getvariable{Crop}{mark}{cross}
      {\let\PageBackground\CrossMarks}
      {\relax}

For debugging purposes, I just have this

\doifelse{\GetMark}{camera}
   {mark defined as \getvariable{Crop}{mark}}
   {mark not defined: \getvariable{Crop}{mark}}

which will print out a message. \getvariable{Crop}{mark} however, is  
either empty or has the value I predefine when I initialize it, it  
does not take the user-supplied value within the module (if I insert  
this doifelse thing into the document, it does return the correct  
value because then the \setup-command has been read before.)

Thanks, and best

Thomas
