Page Header and Footer Orientation

Hi,

Using CR 2013 I need to write a report where the orientation of the page is dependant on a certain variable, I've done this by creating 2 details sections, setting one to portrait and one to landscape and then surpressing each one depending on the variable.

My problem lies with the page header and footer. I've created two of each but I can't seem to change one of them to landscape whilst leaving the other as portrait (the options are greyed out).

Have I done something wrong or is the options just not available for page headers and footers.

Any help would be appreciated.

Stuart.
