Need help writing an expression for checkbook register with running balance.
Deposit - withdrawal - balance
If this is for a homework assignment... read your assignment.
If this is for a home-built checking account monitor database...
Microsoft Money, Quicken (though I really can't recommend it now that
Intuit's screwed it up so badly), and dozens of inexpnsive, shareware,
or freeware checking account programs are available. It makes NO sense
to reinvent one.
That said...
=[OriginalBalance] + DSum([Deposits]) - DSum([Withdrawals])
is one possibility, depending on the structure of your table (which
you have not posted nor asked about).
