Setting up opening balance for a bank account

Please would someone tell me how to input the opening bank balance?

Have a look at Guides | Manager

This one got me confused as well. It is in the documentation, but its not immediately obvious. You need to set the start date in Manager and then you will be able to add opening balances. I find it best if you read through all the dcoumentation and help guides first before using the program as it will help you to understand how the program works.
