Structure 2.0 - how to add a field for search exerpt??

Hi

EE 1.6.8

I’ve built a site using structure 2.0.

I’m not sure if this is a structure ting or not, but I want to have a default field for search results in each weblog that is structure enabled.

When I go to admin > weblog Administration > weblog management > Administrative Preferences > Which field should be used for search excerpt? is a drop down list with nothing to select.

Am I missing something fundamental here?

Thanks Peter
