Question 1:
The parenthesis are wrong. The _href attribute is inside I and not A
helper. In fact, a parenthesis was missing too.
{{if page:}}
{{request.vars.page = [page - 1] }}
{{=SPAN(A(I(T('Previous')), _href = URL(vars = request.vars ) ) ) }}
{{elif len(rows) > items_per_page:}}
{{request.vars.page = [page + 1] }}
{{=SPAN(A(T('Next'), _href = URL(vars = request.vars ) ) ) }}
{{pass}}
Question 2:
If you are getting the following error: non-keyword arg after keyword arg
That is because you must always write first the "unnamed" arguments and and
the "named" arguments after.
