Re: [Zope] Newbie still having problems understanding namespaces

Hi David, try <dtml-var expr="_.abs(-23)"> David Lambert wrote:

I'm sure this is a case of RTFM, but I think I may be reading the wrong FM! Looking at the DTML reference section n the Zope Book (PDF version) on page 228, I see a set of DTML functions which I had assumed I could call, for example:

<dtml-var expr="abs(-23)"> which I would have expected to evaluate to 23.

Instead I get the error:

Error Type: NameError Error Value: global name 'abs' is not defined.
