You should never only say "its not working".

We need to learn in what way it is not working ("Error Type", "Error Value"
and traceback, in case of an exeption).

That said, your problem is probably simple:

  Almost surely, a "prefix=sequence" is missing in your second
  "dtml-in".

  Furthermore, "dtml-in" treats pairs (such as those created
  by "map(None,l1,l2)" in a special way: it splits them
  into "key" and "item". Therefore "sequence_item" is not
  a pair in the case, but the second pair component.
  "sequence_key" gives the first one.
  This discussion assumes a "prefix=sequence" attribute on
  "dtml-in".
