The problem is hooking them all together. Passing the query to a PythonMethod is throwing up the following error:

Error Type: TypeError Error Value: argument l: expected read-only character buffer, instance found /usr/local/src/zope/Zope/lib/python/Products/PythonMethod/PythonMethod.py, line 168, in __call__ (Object: parseLocation) (Info: ((['SB_B208'],), {}, None)) File <string>, line 2, in parseLocation TypeError: (see above)

OK, it looks to my relatively inexperienced eyes that the Python Method isn't getting an argument of the type is expects. Correct. Instead of a string, it gets a class instance.

<dtml-call "REQUEST.set('user_id', user_id)"> <dtml-in "qry_person(uid = user_id)"><br> <dtml-in "buildingCodes(parseLocation(l))"> <dtml-var building><br> # 'building' comes from the Tiny Table </dtml-in> </dtml-in> "l" should be a string but it seems to be an instance. Where does "l" come from?

I'd appreciate it if anyone has any ideas about this. I'm probably making the whole thing too complicated, but for reasons of code reuse, this seemed like the most efficient approach.
