[Zope] ZPT + python script problem

[Chetan Kumar]

Hi all

This fellow (copied straight from Zope Book) does not work !!!!!

------------------------------------------------------
<span tal:define="Times here/GetProjectsPython"
      tal:replace="string:${Times/Hours} is ${Times/Mins}">
</span> Time in hours and minutes
------------------------------------------------------

The python script GetProjectsPython returns a dictionary with
Hours and Mins as keys and their values.
Here is last part of the error message.
