Hello Arch,
You are right that i did a mistake in the first line.

your statement CORRECT! <By "between" do you mean inclusive of the
Start date but not the
Finish date?>


It probably can be done in SQL, but I'm not good enough in SQL to do
it. This function works as you requested, however:


Public Function CalcSum(Tdate As Date)
Dim SQL As String
Const StartDate As String = "Sdate"
Const FinishDate As String = "Fdate"
SQL = "Select sum(money) from q1 " & _
"where #" & Tdate & "# >= " & StartDate & _
" AND #" & Tdate & "# < " & FinishDate
CalcSum = CurrentProject.Connection.Execute(SQL).GetString
CalcSum = Left(CalcSum, Len(CalcSum) - 1)
End Function



SELECT SortedDate,
CalcSum(SortedDate) as RunSum
FROM Query1 ;

SortedDate RunSum
1/1/2008 1
2/1/2008 1
3/1/2008 10
4/1/2008 12
5/1/2008
