On the header widget, it has:
<b:include name='description'/>
And I want to reference it in the post-body (inside Blog widget), with:
<b:includable id='description' var='a'><data:a.description/></b:includeable>
But it wont print out the post description, is the code wrong? or it just cant be referenced across widgets? I've tried modify the header widget <b:include name='description' values='description'/>
and I got blank page instead
Right code for post description is <data:post.snippet/>
(140 characters) or <data:blog.metaDescription/>
.
