This one is a bit more difficult: you need to look at the source code to find out what goes wrong. The traceback again tells you that the problem is with "here/?number/macros/author". Moreover, it tells you that the exception is raised in line 107 of "Module Products.PageTemplates.Expressions". The code, you see there is "path[i:i+1] = list(val)". I see from this code (it is okay when you do not yet see it), that "list(val)" is the problem. You must now look a bit around and take names seriously. The code aroung is: if self._dp: path = list(path) # Copy! for i, varname in self._dp: val = vars[varname] if isinstance(val, StringType): path[i] = val else: # If the value isn't a string, assume it's a sequence # of path names. path[i:i+1] = list(val) This loop is responsible to replace the "?varname" occurrencies in your path by the value of the variable "varname". As you see, the value may either be a string or a sequence of paths. In your case, it is an integer and "list()" results in the "TypeError" you observe. Add "number python:`number`" after your definition of "number", i.e. I removed the "global" (as you no longer need it due to the introduction of "tal:block"). The "`...`" is a Python operator equivalent to a call to "repr(...)" which converts into a string. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Newbie: Missing a Variable (TAL/METAL Question)
Alexis Rhoda's suggestion sounds similar. I edited the code as follows, both with and without the 'global' parameter with the same error thrown. I read the material you recommended before writing the list and have been referencing it. I confess that snakes would bite me repeatedly though before my eyes for lack of seeing them, no matter how hard I try. Your further help would be very much appreciated.

You must be very careful: both in reading and in writing. And you must try to understand how things work. And you must provide full error information (i.e. "Error Type", "Error Value" and the traceback -- you find all of them in the "error_log" object in your Zope "Root Folder"). If you use "repeat/variable" (again, "variable" is not meant literally, but *some* "variable"), then "variable" must be a repeat variable defined by an enclosing 'tal:repeat="variable ..."'.
