"dtml-tree" needs an object not an object name.

When I last looked (a long time ago), it did not accept the
"expr" attribute.

You can try:

    <dtml-let
       treename=treename
       treeobject="_.getitem(treename)"
    >
      <dtml-tree treeobject ...>
        ...
      </dtml-tree>
    </dtml-let>

The "treename=treename" calls the script and binds its result
(a string as you say) to "treename". The 'treeobject="_getitem(treename)"'
resolves the string into an object and binds it to "treeobject".
