Ťstandard_html_headerť in DTML too. I don't think you can include a
ZPT document this way.

<excerpt>Hi,


I'm trying to figure out how a shopping cart is working in Zope.

I've looked at the "Shopping Cart" Example in Zope (2.5.1).

The "index_html" is in ZPT language and I rewrite it as a DTML 

Method/Document.

The page seems to work until I push the "Add Items" button, on the
next page 

I get the error message:


Error Type: KeyError

Error Value: standard_html_header</excerpt>
