yes,
that is the thing i try to do.
the actuall date and one month back is no problem.
i believe the problem is that i had to set the return from "def date_manage():" as "global " .
the parse_index is locking for INDEX as an global variable.
please do not laugh at my pathetic attempt

this all is great to lern something. It's fun if you're always a little further than yesterday.
but for an alltime beginner it is very hard.
all i want to know at this stage is:
is it the right way?
or even to complicated in thinking?
