RUNNINGSUM Question

HSMorales

I have a table with 10 fields.

Field "Current_Balance" is what I need to compute.

Field "BEG_BALANCE" holds my starting balance which I will use to initialize "Current_Balance" to start.

Fields "Debit" and "Credit" must be added or subtracted from Current_Balance in each detail line.

Where do I initialize "Current_Balance" ? Table Header maybe ?

is RUNNINGSUM the best way to do it or should I use a PersistentGlobalVariable. ??

If I use a PersistentGlobalVariable, where (using script) do I initialize it to start and how do I add or subtract from it.

Thanks for you help.
