[Zope] newbie question -- database list/report with sort by column header

[John Cappelletti]

I am listing the results of a database query using dtml-in. I'd like to
be able to give the user the option to re-sort the list by clicking on a
column header. ok... I'm starting small with a form and radio buttons to
allow the user to specify the sort.

I've created what I believe to be a global variable for this page using
the property screen. The variable is to capture the column name for the
sort. My simple question is how do I assign a value to this variable
inside of the dtml method! I'm not finding a description of variable
assignment in the documentation (yeah, I must be missing the obvious).

Any pointers would be appreciated.  (also, know if anyone has
implemented interactive sort by column header?)

thanks,
