[Zope] Problem with nested Z SQL Methods

[Thomas B. Passin]

Your problem is not with nesting two sql requests but in tryuing to nest one
<dtml-va> within another.  This is not allowed.  This ought to work, though:

   <dtml-in "Database.sqlGetResults(tid=TID>)" >

After all, you already are able to display TID, right?  So its value is
available when the second call is made.

Cheers,
