How do I keep track of counter in Zope.
For example, if I want to produce the following output:
1.book1Author1
2.book2
3.book3
4.book4Author2
5.book5
6.book6
7.book7Author3
i.e. book1, book2, book3 are by Author1, etc.
I need something like the following
...
count = 0 ---intended
dtml-in "AuthorList()"
dtml-let author="sequence-item"
dtml-in "BookList(author)"
dtml-if "sequence-index==0"
dtml-var count sequence-item dtml-var
author
dtml-else
dtml-var count sequence-item
count=count+1 -- intended
/dtml-if
/dtml-in/dtml-let
/dtml-in
I do not know how to set count=0, count=count+1 in dtml.
Any help will be greatly appreciated.
Thank you,
