Remember, when you put an argument in quotes like <dtml-if expr="myvar ==
'1'">, the stuff in quotes is a python expression.
So, in python, "sequence-item" is actually trying to subtract item from
sequence.

Whenever you are dealing with sequence-item, sequence-key,
sequence-whatever, in a python expression, you need to do this:
_['sequence-item'] _['sequence-key'] and so on...

Considering the above, you could right it like this (untested):
<dtml-in "Folder.objectValues()">
  <dtml-call "manage_delObjects(_['sequence-item'])">
</dtml-in>

Don't feel bad, you aren't the only one.

yes, when you use <dtml-in> to loop over objects, sequence-item is the
actual object ie (untested):

<dtml-in "Folder.objectValues()">
  <P>Object ID = <dtml-var expr="_['sequence-item'].id"></P>
</dtml-in>



Hope this helps...
