[Zope] DTML_TREE loaded from a database.

Hi there, I have an dtml-tree that is loaded from a database table.

From the table I get keyvalues and what method to be called.

I try something like this. <dtml-let object_nkl="0"> <dtml-tree id=object_nkl branches_expr="hierarki_search(parent_nkl=object_nkl)"> <a href=<!--#var screen_to_call-->?object_nkl=<!--#var object_nkl--> TARGET="Right"><dtml-var name></a> </dtml-tree> However when I look at this in the browser the part with the "object_nkl" is lost. Is there someone out there with some tips ? Cheers Fred.
