[Zope] about double sorting

i made a tinytablesplus file, and i want their to be two sorts, the primary sort being last_name, and the secondary being first_name. i say a code the read something like this <dtml-in xxx sort=last_name,first_name> i tryed that, but got an error that said it Error type: AttributeError Error value: last_name,first_name I removed the _names from the tinytableplus file, to make sure it wasnt that, and i got the same error.
