In my original post I mentioned that getCustomerLicenses returns more than one row and I want to create something of a header. > If it only returned one row, then you could do: > > <tr tal:repeat="customer container/getCustomerLicences"> > <td> > Customer: > <span tal:content="customer/full_name"></span> > </td> > </tr> > > ...no need for the condition or the yucky integer indexes.

I'm still getting my head around TAL and how it works so I'm not sure how the "python:customers and customers" code works. Ideally, I want to use just the one Z SQL method (done) but I guess it would be better coding to just reference the Z SQL method once. Currently the page template makes two calls to the Z SQL method. Once for the customer header and another to retrieve the customer license details. Can you suggest how this would be done? I'm also thinking further along the lines too of a page template, printing all customers with headers and details for each. This would use a SQL "GROUP BY" statement. .. But this is still out of my scope of knowledge.
