[Zope] two different trees in one dtml method

[Clarence T. Pate]

Hey all,
I am trying to create two different trees in one DTML Method, and I am
failing miserably.  The first tree works fine, but the second gives an
error message:

'tuple' object has no attribute 'append'.

If I comment out the first tree, the second tree will work.



I have a folder called trouble.  Inside the folder are two folders -
answers and questions.  Inside of the index_html for trouble I have the
following:

<!--#tree answers-->
 <SPAN CLASS="tree">
    <!--#var title-->
 </SPAN>
<!--#/tree-->
<!--#tree questions-->
 <SPAN CLASS="tree">
    <!--#var title-->
 </SPAN>
<!--#/tree--> 

It is not necessary for me to be able to do this, but any help would be
appreciated.

Clarence
