It works very well if you change your dtml-with-line into

   <dtml-with "_[QUERY_STRING]">
or
   <dtml-with "_.getitem(QUERY_STRING)">

(I don't know the difference between both statements.)

That means something like "give me the object with the
name i've put into the variable QUERY_STRING". You can
also use a shorter version which combines everything in
one single python expression:

   <dtml-var "_.getitem(QUERY_STRING).id">

But be careful. There will be an error message if the
QUERY_STRING is empty.
