You must also learn how to formulate questions :-)

I do not yet understand what you want...

Usually, the overall layout is defined in a macro
and individual page templates use this macro and fill slots of it.
Maybe, you read about "metal:define-macro", "metal:define-slot",
"metal:use-macro" and "metal:fill-slot" in the Zope Book.

Otherwise, if you do not want to call "body_content" but
"index_html", then you simply use "pt = content.index_html" (provided
it is a ZPT, too).

In "index_html", you would access "zerror" also via "option/zerror".

When your "index_html" would call "body_content", you would
need to pass "zerror" again.
