First Bank reconcilliation

Hi I am new to Manager Can someone Help as I am having difficulty in reconciling my first bank statement period.
My opening balance is correct as is the closing balance and it shows I have a decreases in balance which I agree but it doesn’t let me take the next step.A window appears and says check lines and balances??
Hope someone can give me light on this.
Cheers

Have you read this Guide: Manager Cloud? There is little anyone can do remotely to lead you through the process. You just have to follow the changing instructions that appear. As you do so, make sure the Cleared and Pending status is shown correctly for bank transactions and that the Cleared dates match the bank statement’s cleared dates. For that, see this Guide: Manager Cloud.

The process can be frustrating, but eventually you should find your error.
