I personally find that this sort of stuff is almost always clearer
when it is expressed in Python instead of DTML.  Most of my index_html
files are actually Pythonscripts that look something like this:

req = container.REQUEST

if req.has_key('some_flag'):
        return container.some_form()
elif req.has_key('some_other_flag'):
        return container.some_other_form()
else:
        return container.main_form()
