Guess what? namespace issues!
I have two DTML methods and a one ZSQL method in a folder. I am apparently misunderstanding how to access the ZSQL method. The top-level DTML method contains references in the following form: <dtml-var expr="show_detail(machine='D340')"> The show_detail DTML method exists to wrap the ZSQL method and convert to a human readable form. It currently looks like this: <dtml-in expr="get_sum_sql(_)"> <dtml-var subtotal null="0"> <dtml-else> 0 </dtml-in> The ZSQL method accepts a single parameter called 'machine'. For each parameter, it will produce a single result. This makes sense to me. Unhappily, it does not work. It produces the following error: Error Type: NameError Error Value: global name 'get_sum_sql' is not defined I'm sure I'm missing the obvious here...

You should use: <dtml-var expr="show_detail(None,_,machine='D340')"> Evertime you call DTML directly, you'll have to submit a context (None = current context) and a namespace (_). Cheers, Maik

Maik in the other email is right, but it's advisable that you don't call a template from a template. Bad design. Consider using Python Scripts instead. Always favouring scripts instead of DTML will help you keep the templates as simple and HTMLish as possible. Peter
The show_detail DTML method exists to wrap the ZSQL method and convert to a human readable form. It currently looks like this:
<dtml-in expr="get_sum_sql(_)"> <dtml-var subtotal null="0"> <dtml-else> 0 </dtml-in>
