Here is my expression:
Net: FormatCurrency(DSum("[Cash]","AccountSummary","[ClientID]= " & [ClientID] & " And [MonthlyDate] <#" & [MonthlyDate] & "#"))
I have it working except for when the month has multiple dates in it. meaning.
02/01/2013......20
31/01/2013......10
and so on..
I starts the DSUM, in the wrong order. It should be flipped.
Thanks
