I have Opening Balance. When I record number of item, I would like to display remaining Balance by subtracting from opening balance. For example, I have 300 apple to sell. If I sell 30 apples today, I want to calculate Remaining balance is 270. Next day, I sell 25 apples, The Remaining Balance is 245. In form, I want to display remaining balance. Please solve my problem.
