[Zope] Acquisition inquisition

I appear to misunderstand how acquisition works in Zope, as it's not behaving like I expect it should. This is what my folder structure looks like in Zope: / + test + education Both / and test contain DTML methods called standard_html_header. A file in /test/education contains the following line: <dtml-var standard_html_header> This causes the header in / to be used, and not the one in /test. I thought that methods were acquired from containers. Since /test contains education more immediately than / contains /test/education, why does a DTML method in /test/education seem to default to acquiring methods from / ? Thanks, Ben
