My solution for this kind of problem is to have a DTML method that delegates
to the
appropriate DTML methods. Therefore each button gets a value and a name, eg.
<input type=submit name=action value=delete>
<input type=submit name=action value=modify>

The DTML method delegating the calls looks like this:
<dtml-if "action == 'delete'">
  <dtml-call "RESPONSE.redirect('mthDelete')">
<dtml-if "action == 'modify'">
  <dtml-call "RESPONSE.redirect('mthModify')">
  <dtml-call "RESPONSE.redirect(HTTP_REFERER)">

The except part catches the cases where an error occurs such like action is
not determined.
Beware of the fact that you might want to pass further parameters in order
to determine the
selected item or so.
