[Zope] Dynamic ordering of DTML-IN?

[Andy Gates]

Another one from the "my brain don't work" side of the tracks:

I have a staff list that I want to be orderable by first or last name. 
So I have buttons for each that link thus:

<a href="staff?orderby=firstname"> etc

The idea is that that feeds over to the DTML-IN tag thus:

<dtml-in "sql_search(search='foo')" sort=orderby>

But this barfs, because it's expecting a field name "orderby" and there
isn't one.  How do I evaluate that?
