Separate running total between two accounts in single sheet

[Nithin314]

The opening balance and running total for 2nd client should be different like in the above image, but when 2nd client row starts running total of 2nd client is showing running total (Rs.1400)of 1st client. We need to separate them. Could you please help me out here.

can you post a sample app
