Access opening balance when report on account is opened.

Access 2013.
A Rookie that put in 10 hours a day since 90 days. Progress good. What is the expression to have an opening balance when I print an account. Many debits and credits happened i.e. till 31Oct2015. Now when I print start date 1Nov to Today. How do I get the opening balance on 1Nov, which is the closing balance of 30 Nov.
