Cascading Input (Addition) (no replies)

I am creating a checkbook and need a Running Balance.
I have created a table control with the transactions listed
and I am looking at the "Cascading input (Addition)" feature
in the Details / Input Parameters thinking that I can use that
feature to display the running balance down the list of transactions . . .

However, there is not much in terms if explanation in the
Help system about that.

Is this possible?

Thanks For Your Help !!!
