Parameters - get last minus one

I have a list of parameters, and they are months. This list is dynamic, and
is based on a query to an OLAP cube.
I want my default parameter to be the last month minus one, so that when the
last month is December, I want to have November as default.
How can I do this?
All help appreciated!

default value
