Can you give an example of the calculation with real numbers and the expected result?
It is not totally clear what it is you want to do.

Solution 1

The running total can be achieved in couple of ways.

It depends on how you want it Server side or Client side.

Both can be reffered in the following link, you may get a fair idea on how to implement it.
