Why do headers and footers of OpenOffice file not fill the variables

Hello,
When I have some [var] in a header or footer then it wil not merge.
Can you tell me why.
I'm working with a OpenOffice candidate in Dutch language.

Hi,

For merging data in yours headers and footers, you'll need to merge
'meta.xml’ or/and 'styles.xml', depend if it's a calc or write document


Only use global var in header or footer like [var.toto]
