Days difference funds lying Idle

[Vapour02]

Hello all professionals, I need help to calculate count of days the funds are lying idle. If the amount is not added for several days. Also if the amount is added it should start with zero again until the next amount is added for the date. Attached is the sample data for understanding.

@Vapour02 I have to say that I would stop my support at this point. I've been developing total 5 WFs according to your request, and I guess you are almost ready to finish your work by yourself! Good luck!
